They're one of the 4 vendors on my "to try" list (along with backwoods brew, viking vapor and vaporrenu). But I have so much TV
juice I really like that I don't know when I'll get around to it.
It's not that I think TV makes the only good liquid. I know they don't. But I have a good success rate with them -- there's only been one flavor I ordered which, based on the description, I expected to like and didn't. There were a couple that I thought I didn't like but they just needed extra aging time. That puts my success rate with them at close to 90%. With other vendors, it seems to be more like 50% (or less, depending on the vendor.)
Combine that with the fact that TV doublers make the liquid so economical and I need to measure the liquid in my apartment by the gallon rather than the milliliter. I really need to make a dent in it before buying more.
