I bought that saw yesterday and cut holes on kitchen cabinet and drywall to install duct for my hood. It worked very well and the blade was easy to install. I didn't experience any problem of blade coming out. 6 amp is powerful enough for me. I like this tool very much. When cutting in a upright position, the sawdust may gather around the shaft. If the machine can blow out air from that area, that will be great. Maybe on high end saw it has.
