Great water bottle
Keeps water ice cold for over 12 hours. The numerous lids give you different solutions to drinking the liquid (hot or cold).

Great alternative!
Pleasantly suprised by this water bottle. I've found it to be a good alternative to the more expensive brands. It's similar in design, shape and color others. It came with different lid options and all of them functional. Even the shoulder strap is comfortable and feels like it won't break easily. As for keeping liquids cold, it works comparably well to other brands. Just use a little more ice and it's perfectly fine. Would buy again if needed.

The Best of thr Best
I've bought so many different kinds from Walmart and Target and even paid more. This right here has been the best 1 and has lasted a long time. I even get more for my money with this right here. Definitely worth every buck!

Does not keep ice over 24hours
Idk what it is I have several cool flasks, the half a gallon and gallon size and I can usually put ice in them and I still have ice in it the next day this particular one ice melts before 24hours. By the 24 hour mark the water is cold not super cold like I like it and my other ones I’ve had.
