Notice in the first You Tube video. The guy tests the Dewalt and he is shooving down on the drill... Then he goes to that neon green brand and isn't even pushing down lol. I like DeWalt and Milwakee. The red Milwakee brand works great my father uses them for construction and never has problems with their sawzall (sp) no drills, lights or anything else. I have used it plenty of times for hole saw cutting, drilling, screwing in things, etc. Never had problems and batteries last a long time.
