Well I gotta say the BuzzPro is one tuff PV and I was amazed time after time when I dropped it that it would fire right up with no damage.I think it has probably been dropped 50+ times since I have got it because I am rather clumsy.Yesterday when I was using it with a 2.5 ohm atty it seemed to be down in power so I thought the batts were low and changed them.When I vaped again it was the same so I got out my under load meter to check it out.On the lowest setting I got 2.7v under load and at the highest I got 4.5v under load which is down a good bit.I took the top cap off to check and clean it and found that from being dropped so many timed the batts broke the pcb free and it moves around so I figure this is the problem.So if your BP seems down in power and you dropped it see if your pcb is knocked loose.I sent an email to Notcigs to get it fixed and i'm gonna miss having VV while it's gone since all my other mods are fixed voltage and adjusted by changing batts.
