ive never personally owned one but have seen them in action plenty of times...which is why i still dont own one. these are straight up facts: 1 they dont get it all and half the time they leave half the stems in the buds which leaves a stick in ur bud every one it misses on. 2 they gum up about 2 z's in to it and if ur hands are sore from trimming with fiskers....just wait till u un-gum an auto trimmer 5 thousand times. u will beg for ur fiskers back..trust me. 3 way over priced. i wouldnt pay 50 buck for one of those pieces of shit and ive seen them for as much as 600$. needle nose fiskers are 12$ at wal-mart and they will last for a few years. auto trimmers, u are lucky to run a pound through it before u are ordering a new tumbler or tenssion spring. dont buy one dude...save ur money. ya just gotta bite the bullet and trim ur ladies up properly. we all know what we are getting in to when we plant our ladies...just dont make sence to try and cheat on the final phase...good luck
