    So far so good, due to weather & point in project, I have not yet to fully test, but look like good quality & seem ok for the few minutes I used 1.

    24 grit sanding disk

    These disks do a fine job. I am using them to smooth down welded joints. They cut fast and the backing is strong so they do not tear.

    Performance at a reasonable price

    The 7" sanding performed equally well as other more costly discs from other suppliers and were delivered in a very timely way
