Quality product
This should have been my first sander, but I have used Makita, Ridgid, and DeWalt. This is the best by far. I bought the adhesive pad and put an adhesive hook and loop adapter on it so when the hooks wear out, I can easily replace. This is really a super sander.

porter cable low profile PSA sander
I wanted to try a brush-less motor tool. It is a little less quieter. I like the lower center of gravity. You have to shut it off if you lift the sander off the object you are sanding for more than three seconds because it goes super fast and will gouge your wood when sitting it back down on your piece. Turning off the sander is no problem because the electronic brake shuts it down quickly. I also bought this tool because I wanted to use my old five hole PSA pad; I still have hundreds of five hole sanding discs. It fit, but I had to remove the white sanding ring just above the sanding pad for clearance. It removes easily by popping it out. The sander works well. I thought the 3.5 amp motor would have more power. It slows down a tad when applying more pressure which I consider normal for added friction. I emptied my filter five times. I like ROB sanders because they remove stock much more quickly than the quarter sheet sanders.
I am glad I bought this sander. It is a great workhorse.

Powerful - Good hand grip-
The sander is powerful and carries the load when dialed up to get the job done quickly. This is a replacement for my older model that died after years of use.
