So tonight my bp fell at about shoulder height onto concrete 8-o I picked it up, my drip tip broke but everything else seemed fine except a small nik on the tank and a few on my bp. Ran to my place (dropped it in parking lot) and grabbed the MM to see if the bp was fine and it is still changing volts fine. slapped on my tank and a new drip tip and it's working just as if i hadn't dropped it. I'm on almost 2 weeks with it and love it. will be doing a review on it sometime next week and we'll see if the drop had any affect with the mod.
