Got it today! It's a very nice mod but doesn't hit too well. Kinda light on the vape-needs more power. I did manage to put an LR 306 on it but still lacks power-not enough push for the 306. The cartos work fine on it, I'm just used to more power. I like the usb feature and can easily use as a passthru. I will continue to play with it using various attachments I have and see what I can do to improve the hits. The feed system seems adequate and installs very easily but only one bottle and needle come with the kit. I suppose that if I can improve this baby I will try and order more when available but at this point I don't need them. I'll report back later.
