Unlike many variable speed tools, this one doesn't suddenly run away. Speed can fairly easily be adjusted to match the bit and material being worked. It also has impressive power and hammer-drills concrete and masonry nicely. My only gripe, and the reason for only four stars, is the bad location of its LED illuminator. The light is blocked by the drill body and the chuck unless you're using a bit almost a foot long. The LED is bright enough to cause pupils to contract, so the deep shadow it creates makes it more difficult to see the bit than it would be without the light. In fading daylight, I need to cover the LED to see what I'm doing.

Used it the day I got it. Loved the power and feel of the drill. Battery life was expected and matches the rest of my collection nicely

It went through red brick like butter

I bought this because I needed to anchor some brackets in a concrete floor. It has performed flawlessly, and quickly for a drill of this size. I highly recommend it
