this vevor rotary hammer, that i brought at a low price is amazing. i have a very bad left shoulder & this hammer was easy to use & hold uprite. for the price i'm suprise that there's isn't a back order for this hammer. this hammer is the machine every one should have you can drill, hammer drill & a darn good rotary hammer. believe me this hammer weights around 13 pounds, hold in any position & start drilling. one of the very best hammer drill that i've ever own
