6 Inch (150mm) 3000 Grit High Performance Waterproof Hook & Loop Sanding Discs Heavy Duty Silicon Carbide Round Flocking Sandpaper for Wet/Dry Sanding Grinder Polishing Accessories, 20-Pack

Not that good, they do not last very long, they loose there grit very fast, which slows the job, not a good value for the price,. I believe its what they are made of which is the issue.

The grit on these was really good. I used some to finish some metalworking and polishing. For rust removal, I used some WD-40 penetrant as lube. The oil did not break down the grit and everything held together for quite a long time. These are pretty decent pads and a good value.

Was pleasantly surprised by the performance of the 3000 grit sandpaper. A great value Does not last as long as 3M but only cost a fraction. Also is out performs Mirkas offering at 3000

For the first time using these disks, I really liked them. They lasted a long time without having to switch them out. The ease of attachment and removal with the hook and loop made them a pleasure to use.

These are very high quality. An excellent upgrade from the stock disks that came with the grinder I bought.

it works good

I used this to cut automotive clearcoat prior to buffing. It worked very well and held up similarly to the comparable 3M product at a much lower cost. I will buy again.

I have only used them for cleaning up headlights. They worked very well.

Work well for the price, used for sanding automotive 2k clear coat. Dry sanding is easier to see the progress ,but wear out much faster than with water.

they hold up great
