Sara Gresswrote a review of Backcountry Backcountry.com Hydro Flask 18oz Wide Mouth Bottle w/ Coffee Lid on December 8, 2013
Familiarity: I've put it through the wringer
I use this literally every day. It keeps my coffee hot for hours and also when the trek across town is 0 degrees. I've dropped it multiple times onto asphalt, resulting in a loud clanging sound, but not a dent. The best part about this bottle is that it doesn't leak! It's seriously incredible, I throw it into my pack and my notebooks/computer are left dry and unscathed. I would recommend this to any coffee/tea drinker who needs to drag their addiction with them anywhere and everywhere.
Only complaint I have is that it doesn't fit into my car's cup holder, since I have an older car, made back when to-go cups weren't the size of a bathtub. However, as I said, it doesn't leak, so instead it gets crammed in other handy spots.
