This is a very powerful jig saw. It cuts really good. I use it for most work as substitute for my circular saw. I found high quality Bosch T shank blades work great on this saw. The thing I hate is the clunky quick change system. But when I use the saw I forget about this problem. It does blow dust but I don't care about it as long as the saw is great. That'swhy I am giving it only four stars.
