Review (5/5): Works great for our toenail and fingernail needs.
[[VIDEOID:7e3241b19b2a32395c9925af72bef3d1]] This nail drill is lightweight, and has a power cord that I measured to be 6-feet, 3-1/2 inches long.
Note: no adapter in included for the USB end of the cord. I had to provide my own adapter in order to plug this power cord into the outlet.
Inserting a drill bit into the nail drill takes a little bit of effort, as does removing the bit from the drill. Once I have the bit properly seated in (i.e. I insert the bit into the drill, leaving 3-mm space, as shown in picture #6 at the upper left corner of the product description page), and start using the drill, the bit stays securely in place.
I like being able to increase / decrease the speed at which the drill bits rotate, using the speed control on the power cord. Some of us have thin nails, so they use a slower speed so that the bit doesn't put too much pressure on the nail. At its highest speed, this nail drill (along with the mandrel drill bit and sanding band) can reduce the thickness of our fungus toenails of our big toes.
The various drill bits (11 in total) provide enough variety to use on the many different fingernails and toenails of our family members.
Lastly, the user manual has excellent diagrams to describe the parts of the nail drill and some of the drill bits, as well as a step-by-step guide on how to operate this nail drill and the drill bit.
Overall, this nail drill and its drill bits works well for our fingernail and toenail needs
