sorry, hit the wrong button.
penis looks in my mouth

so I prefer round mods over box mods. I have a couple mechanical mods and they do look nice, but I worry about running the battery down too far and as I start rebuilding I worry about shorts and low ohms.
For regulated mods I like the innokin mvp. It looks horrible but it is dead easy and cheap (relatively). I have a provari as my only higher end real mod, the whole clone thing is another thread, and I LOVE the way it is made, it does cost about 4 times what the mvp does.
I like the Aspire nautilus atty. It holds a HUGE amount of juice, has adjustable air, and is an all around nice tank. I have some EVODs that are much smaller, much cheaper, and I like the way they vape. I have a genesis clone and I am not happy with it. It takes a lot more work to build a coil than to just screw a new one in. It's plus is that it is brass and looks great on my brass stingray. For huge vapor, in my case relatively since I really don't chase clouds, I like my RDA. It is more of a pain to drip than fill a tank but it does taste better and has more vapor.
Good luck. Try different things and say I use a xxxx but I want yyyyyy. This will let people know where you are coming from and where you want to go so they can fine tune recommendations.
