The black color comes defective always, the paint peels off very easily. I got one, and the paint came off by removing the barcode tag, I requested a replacement through warranty, and the second one (black as well) seemed fine, but the paint peeled off after the first wash.

I gave it a 3 because everything is great besides the lid. For whatever reason it keeps leaking. It’s also quite hard trying to tighten the lid which is probably why it leaks since I never really know if it’s fully closed. Trying to open it is also hard. Maybe I just got a bad one.
No, I would not recommend this to a friend.

I love this water tumbler. It is so perfect t have water with you at all ties. I love the colors, and the ease of the flip straw. I like that if it’s closed, it’s not going to leak if it gets overturned. Very great product. I can’t live without it.

I got the lilac cup and I love it! It’s easy to clean and I like that the straw is at the bottom and can be taken off. I first though it would all be connected and it be a hassle to clean. It definitely keeps my water cold which is great because I love cold water and I drink from my cup all day at work. The only issue I have is when I unscrew the top, it makes a really loud noise and I’m not sure if it’s because I don’t fill up the water bottle all the way or if it’s something else I’m doing wrong.
I would recommend this to a friend!

I like the oz of the tumbler but don’t like that the straw doesn’t stay attached to the lid
