My wife and I both tried those a couple months ago.
Ours was fairly reasonable priced. 5 pack of refills is $15 US, don't know what that translates to for you, but it's way less than a carton worth of real smokes anyway. My father-in-law started it for us, he's been smoke free since september by using the vapor.
As for smoking anywhere, not really. I still couldn't smoke mine at work inside the plant anyway.
And the flavors of vapors range so wildly. Anything from real smoke flavor, to soft drinks, to FRIED BACON!!!! Really fried bacon is one of the choices I saw for refill flavors, there is something like 240 different ones.
Good Luck, hope it works for you, I may try it again some day.
