The 40-ounce travel tumbler performs exceptionally well, especially in extreme heat. On the day I received it — with temperatures hitting 105 degrees — I filled it with ice and iced tea. After finishing the drink, plenty of ice remained. The tumbler then sat in my vehicle until late the following afternoon. When I opened it more than 24 hours later, most of the ice had melted, but several solid chunks were still floating. Its insulation clearly lives up to the claim of keeping liquids cold for 30 hours.The tumbler holds a full 40 ounces and features a heavy-duty plastic exterior that’s BPA, lead, and phthalate free. The inner chamber and straw are made from food grade stainless steel, and the screw on cap creates a reliable airtight seal. I noticed no sweating on the exterior, and the outer casing of the cup stayed at room temperature despite being filled with ice.I ordered the cloud blue version, which includes both a leak proof sipping spout and a stainless-steel straw with a cleaning brush. The handle is comfortable, and the tumbler fits easily into my vehicle’s cup holder. While I only tested cold retention, its performance suggests it should handle the advertised 12 hours of heat retention without issue.Overall, this is a durable, well-designed tumbler that excels in real world conditions.

I did a lot of research before ordering this tumbler and I’m very happy with my decision to order. I love that the straw is stainless steel instead of plastic and it’s made from high quality 18/8 food grade stainless steel. It keeps my drinks ice cold for hours, doesn’t leak and fits perfectly in my vehicle’s cup holder. The handle makes it easy to carry and it feels sturdy and well made. If you’re looking for a durable tumbler with thoughtful design and quality materials, I would definitely recommend this one!

absolutely love this tumbler. The lilac color is beautiful, and the 40 oz size is perfect because I don’t have to keep refilling it all day. It keeps my drink cold for hours, fits in my cup holder, and the stainless steel straw is a huge plus. I also love that it’s leakproof and made without lead, BPA, or phthalates. This has honestly become my go-to cup every single day.

I got this for my daughter, and she absolutely loves it. The design is attractive, the color looks great, and the overall appearance is modern and well made. The material feels high quality and durable, and it’s comfortable to hold and very easy to drink from.What impressed us the most is that it really is leakproof. She can toss it into her bag without worrying about spills. The insulation is also outstanding—when it says it keeps drinks cold, it means it. Ice lasted well over 12 hours, and the drink stayed refreshingly cold the entire time. Great quality, excellent performance, and definitely a bottle I’d recommend.

After two weeks of reaching for this 40oz tumbler every single day, I have a pretty clear picture of what it does well and where it falls just short of perfect.**Size and Seal**Forty ounces is genuinely useful — enough to get through a long stretch without refilling and without feeling like you're hauling a bucket around. The lid locks down tight. I've carried this in a bag (upright), where it has been jostled, and accidentally knocked it on its side briefly, and not once dealt more than a few drops in the straw area. For a tumbler this size, that matters more than people think. I do wish the seal around the straw was a bit tighter.**Cup Holder Fit**It fits confidently in both my standard and oversize car cup holders, which I appreciated during actual driving. No rattling, no tilting — it just sits there and behaves.**Temperature Performance**Cold drinks stay cold for hours, consistent with the claimed 30-hour cold retention. I haven't pushed it to the full limit, but after a long afternoon out, ice was still present and the drink was genuinely cold — not just "less warm." That's a real-world result worth noting.**Exterior and Handle**Two weeks of daily handling and the exterior looks essentially new — no condensation pooling on the outside, no fingerprint smudges collecting, no scratches showing up from being set down or slid around. The handle works fine for what it is. I mostly grip it when moving the tumbler from one spot to another rather than carrying it for long stretches, and for that kind of use it feels comfortable and balanced enough that it never gets in the way.**Daily Livability**Cleanup is easy, which sounds minor until you're using something every single day. No staining, no lingering odors, wipes out without fuss. It also comes with a brush for cleaning the straw so no nasty build up there.**The One Thing I'd Fix**The straw doesn't grip the lid opening as snugly as I'd like — there's a slight looseness that makes me a little deliberate when drinking on the move. That said, the leakproof claim is really about the sipping lid being closed, and with the lid shut, nothing gets out. That's how it should work. If you carry the tumbler with the sipping lid open and the straw in, any looseness there is on you, not the tumbler. Not a dealbreaker, just something worth understanding before you buy.If you want a large, genuinely leakproof daily tumbler and aren't hard on straws, this earns its place in the rotation.

I absolutely love this tumbler! The pink color is so pretty, and the quality exceeded my expectations. It keeps my drinks cold for hours, the handle makes it easy to carry, and it fits perfectly in my car’s cup holder. The lid and straw work great without leaking, making it perfect for water, iced coffee, or any drink on the go. I’ve been using it every day and would definitely buy another one in a different color! 💕

This 40 oz tumbler has quickly become my go-to cup for work, road trips, and everyday use. It keeps drinks cold for hours, and I love that it fits in my vehicle’s cup holder while still holding plenty of water. The sturdy handle makes it comfortable to carry, and the included straw is great for sipping on the go.The leakproof lid gives me confidence tossing it into the car or carrying it around without worrying about spills. The stainless steel construction feels durable, and the insulation does a fantastic job keeping drinks at the perfect temperature. The soft cloud blue color is also beautiful and gives it a clean, modern look.Overall, this is an excellent tumbler for anyone who wants a large, reliable travel cup that performs well every day. It’s well made, easy to use, and a great companion whether you’re commuting, working, or spending the day outdoors.

This BriteLune 40 oz pink tumbler is a decent dupe for other mainstream Stans… I mean brands… Anyway, it feels sturdy and has a nice grippy bottom to keep it from sliding around. It is convenient to have both a straw hole or just a regular drink hole, but the regular drink hole is small and awkward to drink from. I don’t think the cup vents very well if you don’t have a straw in and just use the regular drink hole. I prefer to drink from a straw, and I do like that the straw hole is centered and not on one of the sides. The included straw is fairly narrow, stainless steel with a silicone lip cover. The silicone cover will come off and is not really secured on the straw, so I don’t love that. Also, I would prefer a larger diameter straw. You can fit the larger straws in this hole, but they compromise venting and end up being difficult to drink from. I’ve settled on a reusable plastic straw I had from another set that’s not extra wide but also a little wider than the included straw. Over all, aside from the straw issues, this really is a nice cup in a vibrant pink that keeps your drinks nice and cold for a long time.

So I came across this Tumblr cup. I’m absolutely glad that I did because I have an obsession with Tumblr cups and this one was an easy yes for me, I love everything about this Tumblr cup. I love the size it’s perfect. It holds a lot of liquid. I love the color of it. I like that. It is a soft baby pink color. It keeps my drinks cold for hours on end. The quality of this cup is absolutely amazing. I haven’t had it. Rust or get scratched yet. I do feel like it is a very durable cup and will last me a long time. It comes with a great straw and the lid is super secure. Overall, I would highly recommend this cup because of its durability, the color, the size, and it’s also a great value for your money.

This is a nice 40 oz insulated tumbler with a handle, straw, and dual flip-top lid. With the lid closed, it is spill proof, which is useful for carrying it around or putting it in a bag briefly. It is obviously not spill proof when the straw is inserted, but that is expected. The dual lid design works well because you can either sip directly or use the straw.It fits in most cup holders, and the insulation works as expected for keeping drinks cold or hot. The Tea Rose color is attractive, and the cup feels durable overall. At just under $40, I think it is very expensive, but when it is on sale under $25 it competes much better with other major 40 oz tumblers.The main issue is the dishwasher-safe labeling. The box and listing claim it is dishwasher safe, but the bottom of the cup itself says hand wash only. Because of that contradiction, I would treat it as hand wash only unless the manufacturer clarifies.Pros:✔ Spill proof with the lid closed✔ Dual flip-top lid allows sipping or straw use✔ Straw function works well✔ Fits in most cup holders✔ Insulation performs as expected✔ Nice color and durable feel✔ Good value when on sale under $25Cons:✖ Not spill proof with the straw inserted✖ Full price just under $40 feels very expensive✖ Dishwasher-safe information is contradictory✖ Cup itself says hand wash only despite listing/box claimsConclusion:A solid 40 oz insulated tumbler with a useful lid design, good cup-holder fit, and expected insulation performance. It is hard to recommend at nearly $40, but on sale under $25 it becomes a much better value. The only real concern is the unclear dishwasher-safe labeling.

Not bad! I have some pros and cons: first for the pros: This water bottle is HUGE! Definitely big enough and holds enough water and ice to last me half the day. It comes with a straw, cleaner and straw tip. The color is super cute and looks like a premium bottle. The finish is pretty tough so far and has survived being knocked over a few times. I love the options for using the straw or sipping directly from the lid. It’s pretty leak resistant so far and only leaked out the straw when it tipped over. Great for the gym or a day out.Cons: not much honestly. The silicone grip on the bottom started peeling back the first day but I just stuck it on again. I feel like that will eventually fall off. This also doesn’t fit in my cup holder very well. Not because the bottom doesn’t fit but because it’s so tall that the cup doesn’t fit under the dash! Small potatoes.Overall I’m very happy with this thing!

I’ve been using this tumbler for a few days now, and I’m so pleased with how well made and easy to use it is. The first thing I noticed was how sturdy it feels. The handle is solid and very securely attached, and the overall construction has a nice weight without being heavy. The color is gorgeous in person, and the whole tumbler has a fashionable, high quality look.One of my favorite features is the stainless steel straw. I love that it’s not plastic, and it pairs perfectly with the stainless steel interior. The lid is really leakproof too. I accidentally tested this while carrying groceries and realized the tumbler was upside down in my hand. Not a single drop came out. I was pleasantly surprised.There was a few things to note for accuracy though:• The listing states that the tumbler is dishwasher safe, but the bottom clearly says hand wash only. Not a dealbreaker for me, but worth mentioning since hand washing may not be desirable for everyone.• The product video claims the tumbler keeps ice for 24 hours. I tested this twice using a full cup of nugget ice, and the cubes melted within about 30 minutes once liquid was added. They lasted a few hours without liquid added. That said, the water itself stayed cold overnight, which is really what I care about. I just want cool water ready for me in the morning, and it absolutely delivers on that.Despite those two discrepancies, this tumbler meets my needs perfectly. It’s a great size, fits in my cup holders, feels durable, and comes with a long straw brush that makes it a complete set. For the price, I’m very happy with it, and I absolutely love it.

I have a collection of reusable water bottles and all of them have their good points and their bad points. The tumblers where you have to unscrew the lid to drink, do the best job of keeping the ice frozen, so the water stays cold. Those are the kind I use at the gym. The ones with the straws are easier to drink from, but they don’t travel as well without spilling and they don’t keep the drinks as cool as the other kind. I have one of those that I keep at my work; the ice always melts way too quickly but I can keep drinking the whole day long without any effort.This pink water bottle attempts to be the best of both worlds because it provides two different drinking options, what my kids call “sippy cup mode” where you flip up a portion of the lid and drink directly out of a rectangular hole near the edge, and alternatively a spot to insert a straw which is centered. I have a similar water bottle that I like very well, but in that cup, the straw inserts with the lid still closed (with a slider portion which seals when not in use), and you flip up the lid to drink in sippy cup mode.In this tumbler, the set-up is a bit different. To drink from either the straw or the sip hole, you need to flip up the lid, which attaches down on the far side of the cup. There is no drinking with the lid down. The access port for the straw is made out of silicone and seals when not in use; the “drink directly from the opening” hole is open as long as the lid is flipped up.This water bottle is very good for travel as it is completely sealed and insulated when the lid is flipped down. But the downside is, if you want to use the straw, you will either need to travel with the lid up and the straw inserted, or you will need to bring the straw with you separately.The straw for most reusable water bottles is made of plastic. This tumbler offers a big upgrade in that the straw is made of metal and includes a silicone tip in matching pink. I’ve actually bought metal straws to replace the plastic ones my tumblers came with; that’s a nice upgrade. The silicone tip avoids the problem of the metal straw being too cold, which can be a problem for people with cold-sensitive teeth. There is also a pipe cleaner for the straw, which is a nice bonus.This set up is worth trying and offers great spill-proof durability that I find quite attractive. I like it for travel and for drinking once you get there.

I was looking for a new tumbler to bring with me to work. I found that the current one I use isn't super convenient as it's a bit on the smaller size and I would end up having to refill it multiple times throughout the day.This one comes in at a really nice and large 40 ounce size shaped to easily fit into the car's holder making it great to commute with. The handle is easy to grip and comfortable to hold, and it's kept my water nice and cool even after several hours of sitting inside of a warm car in between heavy traffic. The size makes it super easy and simple to clean. I think the only minor gripe I have is that twisting the lid on doesn't feel as smooth or easy as I've experienced with other tumblers in the past but otherwise, I'm very pleased with it.
