I get the whole physical limitations thing as someone now with only function use of one hand, rebuilding is not a viable option in most cases. That said there are much better options out there with excellent quality and durability. Personally I like the Aspire
nautilus Prime X. It's a trusted quality brand, it has a quality build, hand friendly, ease of use, no leaking even if I leave it on its side or sitting for a while, external battery, lot of options such as RDTA, RBAs and 510 adapter, can use 2 different drop in coil types BP and
nautilus that are readily available in different ohms and reasonably priced, has survived many drops without a scratch plus no
tank on top to mess up when dropped and I'm sure other members here can give you other recommendations to suit your situation/limitations
