I've been using these for 6 months and I love them for my intended use. They do not leak and are very easy to clean. They do stay cold for a few hours. They do not not prevent ice from melting. Your drink will stay cold but will be only cool if out in the sun after 4 hours. I made a drink with ice and left this in a hot car for 6 hours, and my drink was still cool and drinkable......but not icy cold as if in a glass of ice. Does it work: yes. Is it the best option on the market: no. This will not prevent ice from melting...and that is the only negative issue that I have.

I really liked these bottles. Bought 4, one for each member of my family plus an extra. The lid is poorly designed. Only lasted 6 months. The lid off my extra bottle lasted 5. The warranty is a joke. Reached out and filled out there form. I was then contacted and had to provide my information again. I was promised a new lid, in a different color. Didn't mind thou as it was a free lid and I could continue to use the bottle. That was almost 2 months ago. Guess the warranty isn't that great. Neither is a water bottle without a lid. Very disappointed.

I got these the other day and they're better than I expected. The wife and I was looking for something that we could take on a trip that was like the hydro flask but at a better price point. These are prefect, slinger but holds 26 oz. flip top and you can drink out of it instead of with a straw. Plus the lid locks so it keeps it from opening by it self. I'll find out down the line if I have the same problems others have had. But for right now it's all good!!!!

I bought my first set about 3 years ago and have bought more since. I am a teacher and use one daily and my hubby also uses one daily for work. They keep drinks cold and ar a great size. I’ve dropped them and they are dented from so much use, it still going strong. I have had no broken lids as one reviewer did.

Kids love these bottles and happy to use them.

I like the bottle, just wish it had more ounces and kept it colder.

The silicon sip insert was omitted from the order. Water all over.

This water bottle stoped being spill proof after about a year. Also the plastic peace that helps open the bottle broke after a month. So it really doesn’t auto open anymore. Avoid

These are wonderful at first. They keep your drink very cold and are easy to carry around. The issue is that after a bit of use, the rubber piece on the lid breaks which makes it difficult to use.

Great product. First bought for my daughter and I to use for our Zumba classes. Liked them so well that I bought three more sets for Christmas gifts last year and will be ordering another set for church Christmas boxes this year.
