I have only used this sander once since it came. It came on time and well packaged. WOW! It makes short work of a heavy job. I have a wooden platform area in my house that has some water damage and I need to refinish it before I sell my house. It took me a long time (over an hour) and many sheets of sand paper to remove a little patch of damage with my finish sander. My finish sander finally died and I was reluctant to spend the money on a Porter Cable sander but I did the research and finally decided it would be very worthwhile. I could've used this sander SO many times in the past and instead, I grueled over jobs with a finish sander that was not capable of doing what I wanted it to do. I am a female and I am the handy man in my house. I wanted a powerful belt sander that is competent enough to do the jobs I need it to do around my house. I love it, it appears to be VERY well made and it sounds SO good when it is running, like my circular saw. Changing the belt is super easy, just move the lever (that's made of metal btw, not plastic like other belt sanders) and put on a new belt. Alignment is easy too, just turn the knob while it is running and it aligns perfectly. What people are saying about the variable speed dial is true, it is out of reach when in use but this does not bother me, I don't think I'll need to adjust it while in use (I usually know what to adjust it to before I start sanding) and if I do want to change the speed I'll do it when it isn't running. I recommend this Porter Cable sander to professionals and to do it yourselfers.
