My v2 threads wore out, but I replaced the topcap. I ordered a v5 in the meantime. It is working, I just had a scare this morning. I still want a more reliable device.
I have nothing against Innokin. They seem to be the goto VW device in my price range otherwise I'd be looking at a DNA20 mod or REO. There doesn't seem to be anything in between.
I'm protesting Provari until they release a VW. Then I hope I have the courage or $$$ to
step up.
I've been using the AGR tanks. I think they are smaller then typical custom tanks. They should work.
There's others in your range, but there's few that give you the bang for your buck.
An MVP2 has a 2600mAh battery. This is larger than a typical 18650 by 400mAh. Add to that the fact that the charger is self contained, so you don't need to carry a charger around, the thing runs while your charging via USB pass through and it can even charge your other electronic devices.
Sure, it's an internal battery so when it wears out you throw the whole thing away, but at the going price of $45.00 how can you go wrong?
I've got two. Each one rotates. So I never have one charging more than once every 4 days, which extends your projected charge cycles into years. And, at $45.00, if one takes a dive into the toilet or some other such nonsense, replacing it won't set you pack more than a carton of smokes.
The vv3's are nice, but at 800 mAh, they won't last as long, and you would need to buy several units to keep in rotation to ensure they last. I still have a vv3 as my emergency unit at work. Since I have a desk computer, I can easily vape it on passthrough if I need to. I have a Mini Protank 1 (another backup) on it filled with juice.
That way, should I ever leave for work and forget to take the MVP 2, I have something at work that will fill the void for a day.
