These sanders have a bag of various grit sanding pads. This almost immediately became a go-to tool. I wouldn't buy this again, but it works fine. I didn't notice any bad characteristics. Best of all, I am glad I came across the Festool line.

Festool 575382 Final Thoughts
The sander is light and saved us hours of time. I have owned this sander for a little over 3 years. Covers a large area fast, dust collection pretty good. I didn't notice any bad characteristics. They called me thanking me for the lead!
