I had a lot of ideas for a APV, I started with a Vision Spinner II. I would say the Innokin iTaste MVP 2.0 great box mod really, I was looking at the iTaste VTR because it was the only APV in my main shop then was referred to my towns ecig shop and they had iTaste MVP 2.0 a lot of people suggest it and I now know why.
Green-Yellow-Red battery light;
Really light and durable, very firm;
A starter kit is 70-75$ with iClear 16 or iClear 30 tanks and are really good tanks with great coils; 3.3-5 in 1 increments VV (variable voltage) and 6.0-11.0 VW (variable wattage) in .5 increments.
I'm using a Nautilus Aspire tank 5mL with 4 airwaves, I use the smallest one, and I set comfortably with most eJuices at around 3.8-4.1VV and 7.5-9.0VW
Great price, really simple. If your looking for more I don't know what to say really
