Great Quality
This review was originally going to receive 4 stars because one of the attachment pieces did not fit into the drill wand. However, I contacted the seller and they offered to provide me with a replacement.  The device is high quality and does not appear or feel cheap. The attachment pieces are sharp and fit securely into the drill wand. The device has settings for the user to control the speed and direction. With the quality of this device , I imagine that I will get a good couple of years out it . My nails only need maintenance about every  1 1/2 weeks.
