Christopher F. ★★★★★

The 9-inch length on these AO sheets is perfect for my detail sander, and the 36D grit chews through old paint fast without clogging. I grabbed a bulk pack so I’m set for a while, and they hold up better than cheaper paper I’ve tried.

Jacob ★★★★★

These sheets are a solid value—the 36D grit tears through old paint quickly and the 9-inch length covers a lot of area before I have to swap them out. They hold up well for the price, and I like having the option to order more in a bulk quantity.

Michael F. ★★★★★

Cutting these to size for a tight corner was easy, and the 40D grit chewed through old paint without loading up too fast. They’re a solid value if you need a bunch of sheets for rough work, though I’d grab a finer grit for finishing.
