I'm surprised that you like your stanley flasks, I don't!
Yes when it's working it's great but unfortunately they are poorly made & are unreliable. I'm on my 3rd one as the first 2 failed (not keeping stuff hot) and were replaced under warranty. Ok there's a lifetime warranty but that's not much use when I've been standing out freezing at a rally in November & I'm looking forward to a hot cuppa! They all failed after maybe 100 uses, very poor quality & there are many others online who have had the same experience. I bought it at a local hardware shop & they stopped selling them due to so many people returning them broken within a few weeks!
On the other hand I've a 35 year old Thermos branded flask & it still works perfectly.
