Lol, dont get me wrong Evolv's boards can and do have issues...for instance my first Evolv based mod, a DNA40 mod, lasted a month before dying, and the replacement board they sent (actually they sent two, becaase the first one went missing i the mail, but they just sent another one without any hesitation or drama) never worked, but at least i actually got more usable vape time out of that, than i did the JoyeTech VTC Mini....
With JoyeTech if you have an issue, youre likely to get ignored for weeks on end, have your technical questions answered by the JoyeTech marketing department whos only advice to any mod is issue is to tell you to "buy an Ego One tank", and weeks after that, and after more hammering away at them you get then sent strange customised firmware that oddly seems to try to correct the exact numeric resistance drops you personally report, which are particular to you (and wont benefit anyone else), and youre told you cant talk about this "beta" firmware to anyone - im not the only one this happened to after weeks of hammering away at JoyeTech. I also outed their "you cant share or talk about the "beta" firmware email and firmware to pbusardo, who i happened to be talking to at the exact time the fishy JoyeTech email arrived, just so someone else knew the underhanded way the issues were being dealt with...under cover of darkness and with request "not to share the firmware or talk to anyone about it".
Evolv over JoyeTech any day, they will at least answer emails from day one (and your emails wont be rerouted to the Marketing Dept whos only answer to anything is to "Buy one of our tanks" whenever one of their mods plays up), no weeks of being ignored, and they will replace parts
