The thing about those B&M taste testers for me is that the juice often tastes radically different in those testers than it does in my sub-ohm RBA. I bought some Virginia tobacco flavor at the nearby vape shop, and it tasted just great in their tester, but when I got it home and put it in my .8 ohm AGA-T2 on my mech it was the most horrible stuff I have ever vaped! Bar none! It was hideous, wretched, deeply weird, and seriously nauseating. I can't begin to describe it. Yuckie!!! Ptuuuuiiii! Puke-O!!!
That was not the last time I had bad luck between the B&M testers and my own rig. Fact is .2 ohms can make a real difference in juice flavor, and they are prolly using 2.5 ohm coils in those testers, while I'm running at .8 ohms. So juice shopping is not an easy thing for me, unless I buy 10 ml just to try it out there in the store. Bummer in the summer....
