This bottle is super tough, it has a super thick rubber outside that absorbs drops. The color can be seen in a crowd, and has an excellent spot for a name. It’s small enough to toss in a bag and seals perfectly so there are no spills. With all that being said, it does not keep liquids cold for very long. This was super disappointing.

The top doesn’t come off after a few uses. It turns and turns but nothing unscrews. Waste of money.!

I’ve actually had a flaw with cleaning my kids bottles. We have 2 and both lids on the top where the straw is have gotten dirty and stained. Now this is their everyday water bottles but they shouldn’t stain the way they are. I’ve gotten toothpicks and tried cleaning them but it didn’t work. There should be a way to detach the straw to clean it properly.
