Hi fellow vapers

, trying to make my mind up. Emode,vtr, mvp v2?. Have been looking for a vv mod for a while now but with the number of choices out im having a hard time deciding. The three up there are my final choices but each have something that I like. Any input would be appreciated.
What exactly is it that you are looking to get out of your vaping experience?
What is it about these 3 that you like/dislike?
A few things to think about...
built in battery vs rechargable battery : can't vape while waiting on built in battery to recharge, where as with rechargable batteries, pop in a spare battery and vape away while the battery charges
built in ohm checker? very nice feature to have
the higher the mAh of the battery the longer the battery life before recharge
built in battery protection?
vv ranges (3.0 - 6.0, ect)
type of threading...is it 510, ego, both or other? will you need to buy adapters for tanks? or air flow regulators?
Do you like the design? This is your device, you will be using it and living with it...is it what you like?
Price? Is it worth the price? Can you afford if an accident broke and you are now out that money and device and in need of a new one.
