This is awesome! My husband wanted to polish some rocks we've found over the years. So I bought this and some sanding pads. They came yesterday evening. Today he got up, went to the shed and I haven't seen him since. He keeps sitting more and more rocks outside the shed. They're very shiny now! 5 stars all the way!

I am glad I purchased this adapter. Now I can use more substantial attachments for sandpaper or grinding disks for any material. I used this to hold diamond pads for finishing granite. The product looks good, due to use of this adapter.
