This sander is very high quaility, and will last for years. It is very powerful, you can sand anything in about 1/2 time compared to a normal belt sander, because you can put so much pressure on it. It works great and the  dust bag is great, it holds alot of dust and has yet to rip. The sander is  also very stable, ive used it for hours with no fatigue. the speed is also  very easy to adjust, just with a simple flick of your thumb. I highly  reccomend this belt sander.
