Been using EVODs with various stick batteries mostly, for a year. Haven't tried everything out there, but so far I find them cheapest and best. Previously tried CE4 type clearos and don't like them, can't handle long drags and vapor comes out too hot for what it is. Tried an Aspire BVC clearo and I like the vapor output but not the masked flavor. Don't care much for the dual coil Kangers either. I also have a Taifun clone and 2 drippers and have had problems getting flavor out of them. It doesn't help I'm not interested in more than a few times as much power and vapor output than the EVODs. I can get some amazing flavor from the dripper at times, but it's at least as juice-selective as the EVOD. My favorite flavor in all of vaping, if I had to choose, is GeJ Patriot in an EVOD with cotton wick. The same juice has been lame, or even tasteless, in every other device I've tried it in. I continue to search for better hardware because I'd like just a bit more vapor output, or the same in less than 8 seconds, but there doesn't seem to be middle ground.
