I give it 4 stars only because it doesn't have a battery indicator.

I was torn between several models and after reading several reviews, I ended up choosing this one.

It is quite powerful, I didn't expect it to be so powerful for its size.

It is small, but its design and handle make it convenient to hold. I don't have small hands, but it remains comfortable to hold.

I would have liked it to operate at around 200 to 210 rotations, but 180 is good enough. Considering how powerful it is and the lack of control over its rotation, it is still good.

Most models had microUSB power supply, but I was afraid it might break with use. This one has a regular power supply - a plug like the ones electric razors have.

There are 3 settings: tightening - loosening and a dead - center one that allows you to manually screw it in, giving you the ability to use the flashlight. The flashlight is quite powerful and sufficient for seeing where you are screwing.

There are only two heads included, along with the power supply and the manual.
