I had recently purchased the istick pico kit with the Melo 3 tank. I really like this set up, works great! I wanted to pick up a backup tank for this mod and got the kanger toptank mini. This tank looks like it was made for the pico, the fit and finish are great. The .5 coil worked really good, lasted about a week. Today I put on the .15 NI and switched to TC. Locked in my base res. At room temp, and primed the crap out of it. The coil is marked a .15 ohm, but reads as a .22 ohm. Seems to be common. Brought the temp up slowly to 410 F. So far not real impressed. Will bring up more later. Next I will try the RBA that came with the tank. The draw on the Toptank seems a little tight compared to the melo, but I'm good with it. I will definitely be getting a couple more of the pico's.
