I bought this drill to fit kitchen cabinet handles. I can install 30 pens. For each handle, I need to install two holes for a total of 60 holes and install 60 screws. With this tool I have made my work very easy. A flexible nozzle (don't know the name) helped me put a screw in a slot under the kitchen sink where a tool or screwdriver can't get in. Worth buying. The included app helped me a lot to get started. Battery: Has a three-level LED indicator. High medium low. One thing I noticed is that when I was installing a 24th kitchen cabinet handle (the battery level was average at the time) the drill suddenly stopped working. When I pressed the power level button in the battery pack, the battery indicator did not respond. I thought the drill was broken. I was thinking of trying to charge. It worked. I think that when the battery reaches the minimum power supply level, the power will cut off, which is good for battery life extension. I would be happy if the drill stopped working when the battery indicator is low, and even though I've pressed the battery indicator if it flashes, I understand that it needs to be charged. There is a gap that needs to be filled. Note: I'm not a pro, thought I should try and it worked for ME. This review may be useful to you, maybe not to professionals. Thought to give five stars. One star deducted for the battery. I'll be pursuing this on my next project. As the battery indicator stabilizes, the star count will increase to FIVE stars. I hope this review can help someone.
