Thanks for the positive feedback. I'm gald to hear that the Vapor Flask is of superior quality and the people making them really do seem to care.
You'll be much better off with a Flask than going with hana modz (I've heard they have terrible CS), IPVs (also terrible service - the company contracted for warranty work in the US refuses to honour your warranty and will not respond to emails or calls), Sigeleis (difficult to get any CS assistance), or any clones/counterfeits (if they work for longer than a month you won't be getting any support at all when it burns out after three...)
Despite the fact that Vapor Flask seems to have some QC issues currently I think their CS is good enough to make up for it, at least in my opinion, and the product build quality is superb. It's just the details that need refining.
