Excellent flask, very convenient!
Excellent product! I work from home and picked this one for its size and the fact I have another bigger flask that has served me good. Also, when I am in meetings, I prefer to use the straw which makes drinking more discreet (just my personal thought). I compare it to my daughter's Stanley thermos and find it much better, less bulkier and the straw is more compact and it will not allow the 85+ degrees temperature I am around most of the time to warm my drinks even if I leave it upright for long time. It keeps my drink cold during the day until I finish it, and you can still hear what's left of the ice cubes when you shake it after done. Not sure if it is because it's new and I've been using it for a few days now, that I have to suck a little stronger, but you get used to it easily. The outside looks nice to me and it is perfect to fit in my car's cup holder too. An important thing for my desk: It never sweats, and when accidentally hit, it has never leaked over my papers, nor had a scratch... phew! Cleaning is easy with a brush, like with any other tall glass or container.

Top notch adult water bottle, keeps cold, really cold!
I am so delighted to post this review because I am happy to have tried out this brand. I purchased this for my 10 year old boy and got myself a big bottle of 32 oz and I love everything about it. I liked the options it came with. The color I selected is beautiful like a purple with green reflection background really cool and chic. I like how sturdy, durable and the colors. They really offer all different sizes with is great and convenient. Not to mention, this brand really works great for keeping my water cold!!! I haven’t tried hot liquid but for cold works wonders! So happy and I am definitely an ongoing customer. You will not be disappointed.

Great buy for a kid who loses water bottles often!
I have a teenager so I’ve purchased this same water bottle several times. The quality is great and it’s more affordable than other brands. I like that it has different lid options. It seems like it would last a long time but I don’t have a ton to say about that because my kid loses them way before they wear out. He likes to use a caribiner clip to attach it to his backpack so I will say none of the lids have broken while clipped on to his bag. It’s a good size for school and holds plenty of water. I would recommend this water bottle, especially if you find yourself buying water bottles pretty often.

The Beast of Bottles
This thing is an absolute monster, in the best possible way. I work in a factory setting where the only solid surfaces are concrete and steel; I thought my previous bottle was sturdy but it got destroyed working back there, so I got this one. It has taken a beating but still holds up like a dream. It stays freezing cold for a long time, especially if you fill it with ice, it can endure a lot of blunt damage without being compromised, it’s easy to carry, and the wide twist off topper is perfect for people who need to drink a lot of water quickly. The twist seal can lock the lid on very tight when it’s especially cold, but if you know how insulation works this isn’t necessarily a bad thing. I also love the iridescent color on it, it sticks out very conveniently against the factory scenery as well as compared to coworkers’ bottles. And after all the beatings its taken, the exterior remains completely smooth and unscratched, only a little dented.

If you love water bottles you’ll want this one.
I absolutely love these bottles. I think I have purchased around 10 now. They are really good quality. They keep your drinks cold all day. I’ve gotten them for all my grown kids and they love them too. Last color I just got was sand, very pretty almost has a pink hue to it in person. Right now this one is my fav, coral color but not sure they still have it. Highly recommend

Great Flask, Needs Color Clarity
I really like the flask—the 32 oz size, three-lid options, and sturdy construction hit the mark. It keeps drinks cold and seems durable. I’d call it a solid 4 stars. What works: Excellent build quality and insulation for beverages. Useful lid choices: straw, chug, and flip. Comfortable grip and easy to clean. Why not 5 stars: Color didn’t match expectations. The green I received leans mint—bright and pastel—rather than the deeper, forest-green shown online. It’s fine, but not what I pictured based on the product images Color variation happened despite the model matching, so take note if you expected sage/forest tones. If you’re after the flask’s practical features and insulation, it’s a great pick. Just be aware the green may skew lighter than the photos imply.

Keeps Drinks Cold!
This is one of the best things I have ever bought. Haven't used it for warm drinks yet, but it is great for cold ones. Keeps my ice solid for a very long time. Solid design, nice color, love the handle and the spout you can have up (open) or down (closed). Best insulated mug I have owned. Easy to wash. Buy it.

Sturdy AF!!!
I took this water bottle on a monthlong trip across 12 cities in 3 countries in Europe last year. It was dropped more times than I can count and yes, it has a lot of dents and scratches now, but it has never leaked and still keeps my water ice cold for 24+ hours. It’s also the perfect size for me - doesn’t require constant filling but isn’t too bulky to carry around everywhere. I also like that it comes with 3 different lids to choose from!

This insulated water bottle is a fantastic all-in-one solution for staying hydrated on the go. The stainless steel double-wall construction keeps drinks cold for hours and hot beverages warm without condensation or heat transfer to your hands. I tried both water and tea, and the temperature retention is impressive. The bottle comes with three different lids—straw, flip-top, and screw-top—so it’s easy to switch depending on your activity, whether you’re at the gym, commuting, or hiking. The straw lid is convenient for sipping without tilting, and the flip-top is secure and leak-resistant. Build quality is solid, with a durable, easy-to-grip exterior and a wide mouth that makes cleaning and adding ice cubes simple. Available in multiple sizes, it fits comfortably in most cup holders and backpacks. Overall: A highly versatile, well-built water bottle that combines practicality with style. Perfect for anyone looking to keep drinks at the ideal temperature throughout the day.
