Ok, I just put together a new, stealthy little rig for work. I needed something that would fit comfortably in my shirt pocket, yet give me the versitility that I like. I decided on a Wismec Presa 75tc, and the Kanger Toptank Mini. I had tried the Kanger Ni200 coil that my son had in his Nano, and was pretty impressed, especially since I'm not a huge fan of TC. I have been using this rig for a week now, and it kicks ass. The Presa offers all the settings of my RX200, with 1/3 of the weight. With the TCR set at 650, I'm able to Vape all day at 40watts/460F, on one battery. I get great vapor production, the Vape is warm, the flavor is spot on, an I just don't have a damn thing bad to say. I work construction and 2 days ago my rig fell out of my pocket into a crate of Cast Iron floor drains. It took a hard lick, falling about 3 ft, and bounced it's way to the bottom. Surprisingly it only scratched the paint, on both the mod and the tank, and still doesn't leak, and works like a champ. Awesome setup!
