My new MVP 3.0 Pro was delivered today and I am absolutely loving it. My trusty old MVP 2.0 has been going strong for a couple of years, but when I got into rebuilding I started using a mechanical mod 95% of the time (at the time, the highest power regulated mods only went up to 15 watts). Innokin makes great products at great price points, and the build quality on the MVP 3.0 Pro is absolutely perfect. It hits harder than my mechanical mods for the builds I use (mostly 0.5 - 0.8 ohm single coils) even at similar power levels (set to ~4 volts), and it doesn't lose power as the battery drains.
It is my first high-power regulated mod, and I am definitely glad I waited for Innokin to release one of their own. I just have to get used to the fire button placement (it makes more sense where it is on the MVP 3.0 Pro, but the only other box mod I have ever owned is the MVP 2.0 -- it will take a bit of time to "unlearn" that muscle memory).
Temperature control is the new fad nowadays, but it is still in its infancy -- I will wait until it gets better before buying one. And with Innokin currently working on their own temperature-controlled mod, I'll probably just wait until they release it. Innokin might be "late to the party", but they do things right.
