Ice melts quickly you can feel where the water level is through the walls. I loved this brand but not this set I've purchased 5 of the bigger sets of water bottles that work great. Save yourself the trouble.

I always buy this brand, but they missed the mark on this style. The straw is not secure. It also does not keep your liquid cold. My ice melted within an hour.

The material cover the part of the straw yoh put your mouth on has a bad taste. Everything is drink out of it taste terrible. I'm going to return them.

The top almost always screws on crooked, if you put any drink that is carbonated after a few mins then try to take a drink it just starts shooting out the mouth piece. These are nothing but a paper weight now

DO NOT BUY, THIS BOTTLE SUCKS!!! I bought this bottle for work. The straw part doesn't work and the chug part is small, so it keeps getting blocked by ice cubes and the water barely comes. I ended up just throwing it away.

The cup leaks all the time. We had to get a different cup

Water does not flow easily, suction system is slow and hard.

One of my daughters broke one the first of school. The second one lid is difficult to clean. And grows mold easy

I bought this for me and my daughter. She plays soccer and this is a great way to keep drinks cold. Highly recommend

Straw doesn't work. Upon initial wash prior to using one of the straw inserts was broken the second broke within days. Total waste of money.
