While useful for small projects, this tool is poorly made. I have owned mine for less than a year and it simply quit working. I used it approximately 2-3 times per week, hardly making significant demands on it.
Frankly, it is not worth the price. It might be OK for $9.95 but that is about all I would offer for it. Disks are overpriced and often hard to find or out of stock as well.
This item has followed the general downawrd tend in quality of Craftsman portable power tools. Stay away from it.
