My kids took these to school for only 2 days because one of the lids broke when it was dropped once. My main reason for giving it one star is because they somehow open and leak inside the backpack.

[This review was collected as part of a promotion.] These bottles keep my water ice cold for hours, never leak in my bag, and the quick-fill lid makes them so convenient for everyday use. Plus, the colors are so cute and autistic

These are the worst water bottles ever! They leaked most of the time, the top broke off easily AND the silicone spout part gets all moldy. Please bring back owala at sams.

This is an attractive set of tumblers. I like the "no leak" feature and it is east to fill. However, we are not pleased with this product because I can pack it with ice and fill it with cold water and several hours later the ice is melted and the water is cool but not cold. Very disappointing.

Bought 3 sets of these water bottles and loved them at first - would have given them 5 stars. Filling without having to remove the lid is convenient and it is easy to open and drink one-handed. Unfortunately, after less than 3 months of daily use, 3 of the bottles leak regularly from the "fill" junction (re-seating the gasket doesn't help for long) and 2 of the plastic spout covers have broken, which means those 2 bottles also leak if not upright.

I honestly cannot understand all the negative reviews. These water bottles are great. They keep my beverages cold overnight (I keep them on my nightstand) and during the day. I haven't used them for hot but they were so amazing for cold that when they went on sale I bought 4 more bottles (2 boxes) in the club. As for the leaking I have never had an issue and one day decided to test it out every which way but loose and it never leaked. I think the problem people are having is that the white rubber piece that creates the seal comes loose sometimes. I am not sure why but all I do is pop it back in and then it goes right back to a watertight seal.

These are NOT leak-proof! We bought them for our girls to take to school, where they are supposed to have leak-proof water bottles. These lids leak anytime they are on their side, locked or not. I would return them to Sam's club, but we engraved the bottles before we knew they would not work as advertised.

Absolutely terrible. They leak.

We are very happy with these bottles. They keep our drinks cold all day. Easy to travel with as well.

Lid broke during the first week of school. She didn’t drop it, was just closing it like normal and broke. Super cheap plastic.
