I bought it a couple weeks ago. Dropped it on the wood floor and the hydroflask dented easily. Doesn’t keep things cold as long as I thought it would.

You can test the insulation of your flask by filling it with boiling water. After about 5 minutes, feel the outside of the flask (below the neck). If you feel any hot spots, the insulation has been compromised and you are eligible for a replacement.
This one has become my daily one. I have many Hydroflask bottles and love them all. It keeps my water cold for a loooong time. Only “problem” is they dent so easily. I had this one for 2 days and it dented and I have no idea how since I never dropped it.
