Excellent Sander. The dust collector works well, about as well as the others I've used. I currently do most of my sanding work on a sanding table in the workshop so dust isn't a problem but I've paired my home vacuum to this and it works great in that regard, but the commutator will suffice in a pinch. Eats batteries. I have found that when one battery dies the other is just charging and I go into a rotation process throughout the project. I bought this for small projects so it's ok. If I had a big project or would use it a lot, I'd probably go for the wired version. But all said and done I am happy with my purchase and I think anyone looking for a cordless sander in this mount will be happy.
