The eVic is vastly superior to the MVP 2.0, and has a display that second to none at any price range, but there is a catch. The V1 tops pop off when the device is dropped or even knocked over on a counter top. If done with enough force (not much actually), the lead wires would be literally ripped out of the device, and no one will warrant or fix that for you. I had to learn to solder because this happened to me 9 times on three different eVic V1's, which I fixed 7 times, meaning I still have two broken heads. Even using a strong epoxy to keep the repaired heads back on didn't work. Also, when I got mine on software version 1.1, they didn't work very well....terrible actually.
THE SOLUTION
The V2 came out in June, though the shelves are still full of V1's. They're the ones on "sale" at unbelievably low prices, and for good reason, they're complete crap, imho. I found and bought a V2, my fourth eVic. The V2 has two machined screws in the top at the side of the 510 connection, and so far, so good. Also, version 1.4 is now out, and version 1.3 was outstanding and fixed every problem I had with the device, or any I ever read about. So, that being said, they went from real lemons to lemonade, they still have the best display, the most features, the greatest flexibility and they use a chip superior to the standard China 33.3 chip, which is to say a good chip that is superior to virtually every other China Mod on the market.
SO SAD
For me, the bloom was off the rose. I had spent over $300 on the four eVics, added tubes, including some nice telescoping stainless Kir Fanis tubes, so say another $150 on top of that, but because they had become so delicate in my mind, I would never take them out and, over time, I just migrated to the Provari and Provari Mini, and I haven't looked back. I would never consider buying another one.
CONCLUSION
Forget my sad story. I use Provari and Semovar now. However, a fixed eVic does have the best design, imho, of any tube mod less than the Provari, is feature rich with the best chip in most devices below the Provari. It is not a DNA20 or a Nivel Chip, though, but it's better than the other 99 China Mods (Better chip = better regulated power = better vape). Phil Busardo has a decent video on the eVic that covers the performance specs on the eVic, and some are excellent, some a bit lacking, but overall quite good for it's intended market. There are some really great after market tubes, caps and accessories that are fun to add, so you can really trick it out. The USB charging and computer interface is unique and superior to most other Mods. I'm a little shocked to hear this compared to an Innokin MVP, which didn't even have an Ohm meter until last month, or variable wattage, and was plagued with bad buttons and threads. However, V2 of the MVP fixed those issues, but it's still a long way from the eVic.
The downside is that eVic did not stand behind their product, nor did any vendors, nor did I ever find anyone who would or could repair it for less than replacement cost. I will never buy another first generation JoyeTech device, and the Innokin first generation devices have also been fraught with problems. The Innokin VV V3 (#3) is perhaps the best stick battery on the market, imho, but the first two sure weren't. So, just saying the first generation anything out of China is risky. I used to really trash the eVic and could back it up with my actual story and true facts about the device. However, those issues are resolved, time has passed, forgive and forget, so.....I'm back to saying for someone inclined to be attracted to those features, you'll probably love it and have good success with it. It is limited at 5 volts, though. Of course, you have to make sure it's a V2 BEFORE YOU BUY IT. REMEMBER TWO HEAD SCREWS AT THE 510 CONNECTION.
Good luck to you!
the evic charges through a side flap you plug in the micro USB cable in the box which is used to program and retrieve your data. You can make custom modes and has a bunch of other good features. Bottom cap come off and you can have a spare battery as well. Images attached.
