My new Buzz pro came today along with the M1A1 tank mod, charged up the batteries and tried it out with a standard 510 first and it was ok. Went to Menards and bought a 1/4" saddle valve for $7.02 to punch the hole in the 510 blank, put it all together and filled up the tank. I was surprised how much better it worked with the tank! So far I have only been using the lowest power setting on the Buzz pro and it works fine, not really sure if higher voltage is really needed but nice to know it's there. No more of those flimsy realistic looking vapers for me, get yourself decent equipment to start with and avoid wasting cash on the cheap stuff.
