Specifications by Hydro Flask say
[This review was collected as part of a promotion.] Specifications by Hydro Flask say it keeps hot drinks hot for 12 hours. It does not even come close, more like 2-3 hours. Very disappointed with this flask. My old flask by another brand definitely kept hot drinks hot for up to 12 hours. Even more surprising is that this is a brand-new flask that I received from Hydro Flask to replace my old 20 oz Hydro Flask.

Leaking
[This review was collected as part of a promotion.] Great products but my lid is leaking. Was a gift from me so he just started using.

Good, but lid is impossible to clean
The bottle itself is good. easy to sip from it with one hand. Perfect for morning coffee while reading news. The only problem: it has a "flex sip" lid on it, and the lid is impossible to clean. I have the same problem as in another review by Angela: black gunk builds up in the layers of the lid and occasionally falls out into the drink or clogs the siping hole. (I put milk in my coffee, and I think that adds to the gunk also). This is not a manufacturing error -- this is a serious design FLAW!

Well made product
[This review was collected as part of a promotion.] Used to keep hot drinks hot, helps maintain the temperature and the strap is useful for quick pickups.
