The holes in the pad won't align with any sandpaper I know of. Plan on buying a new pad if you want it to vacuum dust. contrary to the reviews stating valve issues, DONT FORGET TO OIL THE AIR INTAKE. oddly it doesn't mention oiling anywhere on the box. I put about 8 drops of oil in every other use. I put a drop on the valve stem too.

I purchased this sander to make the paint prep easier on my shuttle bus conversion. This sander is of good quality vs price paid and works as it should. I'm not sure how long it will last, but it more than paid for itself in one job.

The only part that I may have concerns in the future is the Velcro that holds pad is very small, holds sandpaper pad well but I think care must be taken to prevent it from clogging, but so far so good. Overall very pleased with purchase, no concerns other than that

Great sander for finishing aluminum and steel. I'm not a paint and body person. I use it to finish metal before bending or welding. I have big hands and this DA fits me just right. I can control the speed fairly well. The palm shape allows me to really fine tune the pressure as well. Very happy with the purchase.

1st day I got it used it to sand a earlyn1900s if not late 1800s pin and cove dovetail drawered dresser I'd been scaping and stripping off and on for several years. One of those rainy day projects I stumbled across in st paul some years back. Finally got the urge to get the remainder paintoff of it and said it and stain seal and varnish it. I used the 6" da off and on for the top sides andb3 drawers leaning on it fairly good with 80grit and up to 180grit. And it blasted thru and barely slowed down under full lean running at 80 to 90psi. It's of solid quality the air control valve for speed is brass and works well. It feels solid in construction and far nicer than others I've used even at cabinet shops and within paint booths I've been in over the past 20yrs the duration of my professional painting experience it works as good if not better than most I've used, and it was under 40bucks. Just came it the original vendor box, arrived in a couple days, with a wrench. And I think that's it. Time will tell how Long it ends up lasting but if you oil it here and there as with any air tool I think it will last quite a while. It's WAY nicer than harbor freights offering and much nicer feel in materials. It's already paid for itself today and I'll use it over my random dewalt electric orbitals for sure. I'd like to get a 5" now as well. Anyways if your on the fence don't be. For the price it punches well above that and it's cheap enough to not worry about. Although after you use it you'll probably feel it's worth more than it is. Great strong relatively quiet da for a good price.
