It's been six months since my initial purchase of the Evic VT, and it's been my daily carry to work ever since. I've had not a single issue with it, and it's been a powerful workhorse and continues to hold a charge like it did on day one. I've used it mainly in VW mode, mostly around 15 watts and the battery last for a good 4 days before I charge it. I never let it fully run down to locked status.
While I used the stock NI200 coil, I hated the Ego One tank. After the fourth month, I managed to buy some NI200 wire, but still haven't built a TC coil onto any of my RDAs or RTAs, mainly due to not wanting to mess with it

Free time is difficult to come by this past year, and I normally have about 6 RTAs and 3 RDAs to build or rewick on a day off, so I just haven't gotten into the habit of using the NI200 for fear of forgetting it's nickle and throwing it on one of my non-TC mods. The Evic VT is my only TC mod.
Anyway, it's been six months and I'm looking to buy some back-ups for the future. I've been eyeing the Wismec Reuleaux and Sigelei Fuchai, but more than likely I'll pick up another Evic VT. The prices are half of what I originally spent, and the battery life, effectiveness and durability have been spectacular.
It's been a crazy year, and I just need some peace of mind for the future.
