I would not purchase another buzz. had 1 and the top cap srew loosened up after changing attys a few times. ejuice ran down the inside of it, also the button was not easy to push after minimal usage (flush with the face of tube). I returned it to get it repaired correctly while under warranty. They were supper fast at returning it but nothing had been fixed. still full of ejuice and switch still sucked, well I tried using it anyway and it worked for short bit then stopped. (same as before)
I set it on my desk continuing to work and brushed up against it, it was smoking hot!!!!. burned my fingers removing the battery cap. I am lucky it did'nt burn the place down. I do not recommend leaving batterys in while un-attended. Buy a mod that sealed so no ejuice can enter inside the tube!!!
