Dropped it once now there sounds like there is sediment sliding up and down in it on the inside of the cup
No, I would not recommend this to a friend.

This 40-ounce Stanley Tumbler is awesome! Not only does it keep my drinks ice cold, but I also really appreciate that the top on this bottle prevents any spilling.

It's fine. I wish it kept cold even half as long as advertised, even with filling with cold water before to prep it. I also wish the straw wasn't so difficult to open. It's overpriced for these reasons, but it's fine.
No, I would not recommend this to a friend.

I take this thing everywhere. Long days at the range and holds ice even being exposed to the sun all day. I have no complaints about these items. They are worth every cent.

This completely lives up to the Stanley name. keeps water cold all day. Easy to clean, and looks great.
