This is a great woodworking sander. I use it in combination with two 5" Dynabrade random orbit sanders. I usually use it with a finer grit after using ROS grinder. It's light and comfortable and the square sole is good for cornering. More comfortable to use than regular 1 /4 blade random orbit sander. You will need a decent compressor, it is rated at 13cfm and I use a 5hp 80 gallon cobalt compressor which has no problem with it.
