Cons

Although it's great for keeping the beverage hot, the insulated cup constantly comes apart & falls everywhere even after I tried to hot glue it. Also when cleaned, it takes along time for water to drip out of the plastic bottom.

2 agree

Condensation sometimes forms on the outer shell and then water spills when you pour

If you find these in the store double check the cup holder as I have read many are cross threaded as the cup will not 'hook' itself on top, hot soup stay hot for me for around 10 hours

I agree that it keeps drinks pretty warm. Not 24 hours, though. The best I've found was like 8-10 hours. After that it's just lukewarm.

That aside...Still lovin' the Rock!

I highly recommend this thermos. I have left it overnight after not drinking from it and have found my tea still hot enough to drink.
