I wish there was an actual good answer to this...
It's a million dollar question in our quest for the holy vape.
All I can say is:
What is your Vape Budget? (some of these mech mods can get stupid $$$$$$$$) This is really the most important deciding factor for me.
What type of firing button do you want? (There are bottom fire buttons, bottom/side pinky buttons and some top/side index/thumb buttons) When deciding this, I like to consider the top device I intend to use on it. If it's something that is best vaped in a certain orientation (like a genesis), then I'd recommend a bottom fire button. If you're just going to use a
tank style or dripping atty/RDA, then a bottom side "pinky" button might be a bit more comfortable.
What features are a must? (you mentioned locking button and adjusting positive pin.) There are also, adjustable air-flow, slots for air flow, recessed 510 connections for eGo style cartos/attys, etc.
Once you figure those things out... Start looking at some
reviews. Good luck! Let us know when you pick one.
