The Pebble looks to be the same size as the Mini Volt. Innokin usually makes good quality products. I got mine from fasttech. The Kit was in stock for $39.99. The mod only was $31 iirc but not in stock. I hate waiting so I got the kit and will probably never use the tank. Also check out the evic basic. It looks about the same size as the Pebble but 1500 mah. It looks like it comes in a 60W version. I went with the Pebble because I prefer Innokin's products to joyetech, but the Basic does look very nice.Nice. Didn’t know about the pebble. I’ve been buying vapresso target mini 40ws for my sister but they’re getting harder to find. That would make a good substitute. Cheaper too. Plus I won’t have to file the completely pointless little nub on the top down to make her atty fit. I don’t know why they did that. It’s not like they were making room for anything. The nub is solid metal.
