so far it's holding up and working great. For the price, this is on par with most pencil sanders on the market. The turnovers are good, there is speed control. It is 1/8 inch and comes with an extra collet. It's lightweight and easy to use. It came in a plastic case and air oil which I would definitely recommend before each use. I've been using it for about a week now and it works like new which is great. I definitely recommend it.
