A pass through ego is easier to charge. And you can't go wrong with an evod.
Skipped to the end...
If you are going to rebuild why not an MVP and a KFL+? Otherwise a nice cartotank would work and the carto are cheap and easy to replace.
I would go the KFL+ route...
Anything with a battery is iffy here, if they connect with the tactile feel of the button and they decide to click it all day long it can become very dangerous.
I would say he could handle the e-liquid without a health risk. But tj stated, may a clearomizer would be better because he may not realize he needs to refill without the visual warning that the tank is empty.
I would recommend a mvp and i30.
The best choice I feel is what you find easiest to tune up or repair. All devices occasionally have problems. I find the i16 and i30 are easy for me and they use the same coil head and it's easy for me to fix any problems that come up. Who is going to set this up for Uncle and help if it's not working right? What do they find the easiest? That may determine your best choice. Any brand/model tank or clearomizer is fine IF its working properly. I never met a good vape I didn't like.![]()
Doesn't the MVP 2 also have the color indicator lights on the button?
Green = battery good
Yellow = battery getting low
Red = time to recharge
?
I would think a protank or a t3s tank something just fill and go then if something happens its not expensive to replace.
