This is the 2nd one I bought - very rarely have I bought the same mod twice. The reason being is that they work very very well, are well built, and have a GORGEOUS baked on type of finish. I've ran tanks on these too but mostly run RDA's on them. My happy place with these is with a build from .12 - .18 .. THAT BEING SAID I DO NOT RECOMMEND RUNNING A .15 COIL AT 6.5 VOLTS OR ELSE YOU'LL PUSHING 44 AMPS AND 290 WATTS !!! LOL .. DON'T TAKE IT PAST NUMBER 111 AND YOU WILL BE FINE.. OK ?? You have huge potential with these mods as they are crazy powerful. I mainly run mine with VCT4's and with good batteries like these it is quite safe. SO TO HELP YOU ALL OUT HERE IS THE VOLTS AT THE DIFFERENT SETTINGS. 1: 3.6 VOLTS 11: 4 VOLTS 111: 4.6 VOLTS 1V: 5.4 VOLTS V: 6.5 VOLTS SO THE .15 COIL AT SETTING 111 WIll BE 4.6 VOLTS PULLING 30.67 AMPS AND PROVIDE A VAPE EXPERIENCE EQUAL TO 141.07 WATTS !! See what I mean ?? It's powerful .. so if you can't do the calculations - DON'T BUY THE MOD. If you're comfortable with this enjoy the hell out of it as it is a fantastic device to vape on.

I had first questioned myself as to why I wanted this mod, but very happy to purchase it now. Been using it all day and so far it's been just flawless. Top quality construction, easy to use menu, looks very nice, and loads of power. Much smaller than I envisioned it to be, lol it caught me off guard but very pleasantly surprised by this device. I put up a photo as well with my Black Kylin RTA on top so folks can get an idea of how a 24 mm atty looks on it, sits nice and flush.

I love this knife and it works well. Double action functions as it should and takes some thumb strength to activate. Very loud and fast when it opens (like a 12 gauge pump) and closes (clang !) so it's guaranteed to grab immediate attention. It came in a box branded Microtech and even had a warranty card with it, but there's no way it's a real Microtech for this price :-) .. This thing is all business and NOT a utility knife. It is huge .. even Crocodile Dundee would nod in agreement and say "now this is a knife". Not something I would flash around any strangers as it has the potential to bring the wrong type of attention. So be careful and don't go getting yourselves in any trouble you can't handle. Glad I ordered it and it will take up a place in my collection.

This is one of the best stackers I own. It hits very hard and is NOT a n00bie device .. know your ohms law and know how to build properly. If you don't know what you're doing with a stacked mod don't buy it. 8.4 volts is nothing to mess with. I have a few "high end" stacks that don't hit like this beast.. Best value for a stacked mod I've ever seen. Great device here ..

perfect for big 3.5mm-4mm ID coils. I use these for a quick wick job for my series builds. For 3.5 I pull a little off, 4mm needs no adjustment and are as perfect as can be.
