Yeah, I just recently jumped into the mech world... picked up K100 with an RSST RBA... gotta say, gives a vape that is far better than any clearo on my Vamo. I am running a .9 ohm coil, so on a fresh battery, it's around 19w... and gives an amazing vape.
Discount Vapors has the K100 for a great price, with a reusable safety fuse included...nice touch, especially for someone new to mechs. I use my Vamo as a backup now, with my RDA on it.
