Review: My Favorite Tumbler - So glad we purchased several of these mugs. Love the color. Love they include two types of lids. Truly leak-proof. Love the rubber bottom which helps prevent tumblers from tipping over. Fit great in our cars. I'll probably go back and purchase more. These are AWESOME.
Review: Absolutely love it! Not sure how long it will last - I absolutely love this tumbler. I wanted something smaller than a 40oz tumbler to carry with me all the time. I can fill it with ice water when I leave work and the following morning (about 14 hours later) my cup still has ice in it. Wonderful! I used it for a hot beverage while trick-or-treating and it stayed hot. Love that it has the two different lids. My only complaint is that the coating has already chipped at the top near the lid. It now flakes off so easy. Overall I love the cup and am now only concerned about the durability. Would hate for it to only last a couple months and then need to buy a new one.

## Questions & Answers

**Q: Does anyone have a comparison about how long these keep ice as opposed to Yeti?**
A: Our Co-Pilot tumbler's double-walled, vacuum-insulated technology will keep your drinks COLD for up to 20 hours, and HOT for up to 5 hours!

**Q: are lids screw on and does this come with a straw? Also it doesn't state free returns for the Dark Rainbow.**
A: Yes, the Co-Pilot comes with a screw-on straw lid with two straws and a flip lid.

**Q: Is the straw silicone or hard plastic?**
A: My co-pilot came with 2 hard plastic straws that were straight. I ordered the the metal straws with a slight bend, which worked so better for me.

**Q: How long does this hold ice compared to other popular brands like Yet (which sucks)??**
A: I've still had small ice cubes 24 hours later!
