I've been using my Milwaukee for almost a decade. He serves me day and night, fighting tooth and claw against the strongest concrete. It never fails me. I have money left over so I decided to buy another one to give my Milwaukee a rest and keep it as a backup. I chose Metabo because it is a brand name. I'm not sure if I made the right decision. Box opened, Milwaukee SDS Plus Bit inserted. It was tight, but I couldn't get the racket out. Maybe it was my racquet, but remember, I used a Milwaukee racquet, not an all-rounder. I called support; they have excellent customer service; I cut the racquet to fit the box and sent it back.
