Insulated Water Bottle with Flip Top & Wide Mouth Lids, 2 BPA-Free Straws - 32-40oz, Stainless Steel, Double Wall, Vacuum Insulated for No Leaks - Keeps Liquid Hotter & Colder Longer - Black 32oz

I purchase two of these and have tested their ability to keep things hot and cold. I’m very impressed. Boiling water stayed hot for at least 5 hours. I filled them up with ice water and the ice lasted 24 hours using this straw. No leaks either! Definitely a good deal! The silver one is a little slippery and the logo was already rubbing off when received but not sending back.

Got the 32oz - it's been absolutely leak-proof with either top that comes with it. Bottle is well insulated, easy to clean and the straw top is comfortable to use on the go. Does all the basics real well at a great price.

Had this water bottle for a little over a month and definitely not disappointed. My ice stays in the bottle overnight, but it does get annoying when you hear the noise of my water bottle moving around when I’m walking. It did leak a little in my backpack once but I think it was because I didn’t tighten it well enough. It was very easy to change the tops as well and I do it pretty frequently now.Would recommend as a good alternative to hydroflask.

The bottle arrived promptly and well-packed. The two tops is great to have as options, but I was looking for the straw top in particular.The bottle itself is rugged feeling and the paint makes it easy to hold. The standard top has a loop to keep it attached to the bottle when open. The straw top does NOT have this retaining loop. The straw top I received appears to leak if tipped to one side, and then righted again: fluid pushes up and out slowly. I worked with the Customer Support (Greg) who was very gracious and communicated well. He is sending along a replacement top at no cost to me. I expect it will resolve the issue. Overall very happy with the bottle. Cold drinks stay cold! Ice lasts over 24 hours even with the straw top. I haven’t tried a hot drink: not why I bought the bottle.I do recommend this bottle, and this vendor.Minus one star due to the issue with the top.

This thing works great compared to bigger named brands no issues what so ever

I am loving this water bottle! I had a larger one in the past by a different company, but it was just too big. I like this size (32oz)- that it holds plenty of water while still fitting into my cup holder. It has kept my water cold for hours without ice. I have not tried it with hot fluids yet.I appreciate that it came with two different kinds of lids!!

This flask really works great. It keeps the drinks cold even in a hot car for hours. It's easy to clean and practice to use. The only bad side, very bad side is the if you are using the straw cap it will leaks very bad. So you always have to keep it vertical position. Kinda sucks.

I have had many, many water bottles, and never have I had one that keeps water cold as long as this one. We were outside all day in 84 degree weather with this water bottle. 36 hours after filling it with water and ice it is still more than half full of ice! I love it! It also holds a lot of water in comparison with many other water bottles. That said it is heavy. Also it comes with a straw option on a separate top but I have yet to figure out how to get the main top off without ruining the attachment holding it on. It seems you have to decide between the two tops and stick with it, or let the solid top flop around while the straw top is on. It's by no means a deal breaker, just a little annoying. All in all though this is my new favorite water bottle.
