      Good powerful dril but parts do not last.
      As noted by others, this drill is great when it works. It is strong. I bought this drill probably 15 years ago and really have only used it a handfull of times (maybe 20-30 times total if I had to guess). And my drill doesn't get abused. But this last time, I was re-mixing drywall mud with a paddle chucked up and in a 5 gallon bucket. This is going to sound like a comedy skit but this actually happened to me last night. I go slow to medium on the low speed setting. Holding the trigger at about half throttle, the drill suddenly started ramping up to full speed and stayed there. I was frantically messing with it while it went nuts, thinking I accidentally hit the trigger lock, so I was trying to disable the lock while it violently danced around the floor between my legs and threw about 4 gallons of drywall mud everywhere. After a few seconds I was able to scootch over enough to grab the mud covered cord and pull it out of the wall. It had emptied the entire bucket around me. Afterwards when I had cleaned everything up I surveyed the drill and found I did not accidentally stick the trigger lock. The trigger switch itself had stuck open somehow. With the mixing paddle removed I plugged it in and the drill immediately went to full speed. Pressing the trigger fully and releasing didn't do anything, its like the trigger switch itself was stuck and the trigger was just flopping around loose. After squeezing the trigger hard, fully depressing it a few times (maybe 6 or 7 times) it finally unstuck the switch and the drill shut off. I was a big fan of this drill until it did this, without any warning! As I said, I bought the drill quite a few years ago but it definitely has not had a rough life and should not have worn out like this yet!

        stopped working after only a few uses
        Drill locks up when trying to drill overhead in high speed mode. Sounds like gears grinding then stops. Works fine if drilling horizontal or down or in low speed mode.

          Milwaukee not what they used to be
          the Milwaukee hammer drill I'm replacing lasted over 25 years. This drill lasted 1 hour. I was drilling holes in concrete and the bit got stuck. when I put the drill in reverse to get the bit out, the chuck came off. I also had to continually tighten the chuck because it kept loosening up. I would not recommend purchasing this item.

            Not so hot
            With little use . The chuck and chuck assembly froze and it was going to cost more than a new drill to repair
