Good enough for what I needed them for

Sanding various wood types.

This was a birthday gift for my husband. He said they work great.

I cannot answer a few of the questions. The pad does not stay on long enough to comment.

I bought these to go on a 3M attachment for my drill, works like a charm, have been cleaning up an axe head. Only recommendation is while using, remember to clean the pads periodically while in use to keep using them longer (I blew through a few before remembering to do that)

The adhesive needs extra adhesive spray otherwise they spin off like a frisbee and hit you. Wear a face mask for sure

Did the job

Their quality would have been great only if they stick firmly.

Tried several now and they keep coming unstuck to rotating disc. Constantly pressing back on. Cleaned disc and it did not help. Looking now for glue stick like we used to do it!

Long lasting and way cheaper then big box store
