Rated 5 out of 5 by from PERFECT for kids! I bought the Pinkalicious and the Purple Acai (not available in this size anymore, apparently?) for my twin daughters TWO years ago. These have been, by far, the BEST satinless steel bottles I have

Rated 5 out of 5 by from I love this product I used this over the weekend and loved it! I live in Az and cycle in the desert all summer. NO water bottle until now has stayed cool. Halfway though a 36 mile ride my water is always warm... No anymore. This was still ice at the end of my ice. The bottle is a tad heavy and it does not have the convince of a squeeze bottle. But the benefits and enjoyment of cold water on a ride out weight all of that. Good job!!!!

Rated 2 out of 5 by from Not as great as expected I have the larger 32oz and absolutely love it, but wanted something smaller for hot drinks or just smaller quantity. When I purchased this I was really excited to try it out but the hot drink was only hot for about 40 minutes and when I put ice water in it the ice melts as if it was in a normal water bottle. Also something I recently noticed is that it sweats when there is ice water and is hot to the touch with hot drinks. I don't know why I have this many problems with this size and not the larger water bottle, could be the size difference. Either way it didn't really live up to it's claims and if I had to buy another water bottle for the price since they are more spendy, I would buy a larger size- those seem to work better.

Rated 5 out of 5 by from Best product if you ask any user! I literally walk down the street and see strangers who comment "I have one too, it is the best ever!". I've never come across a brand that everyone loves it so much they comment to strangers, like we have a secret club.

Rated 5 out of 5 by from Best kid purchase My daughter has taken this to school and adventuring everyday over the last two years. Sport cap has been replaced a few times but this still works perfectly. It's been a smart investment.

Rated 5 out of 5 by from Best water bottel! I have 6 (six) of your products in the different sizes and love them. I've had mine for 3 1/2 years, use them every day. We even have the "Growler size".
