Affordable and good quality.
I love these! They work just as good as one that I would’ve paid $12 for it just by itself elsewhere.

Works great on tough projects- Superior product for the price point.
I have found these disks have staying power, and do a great job at eating through old paint. My only complaint is more about a user error than about the product. In my over zelous utilization I did manage to sand deeper into the wood than I would have liked. In my joy to have found a product that would work on this demon of a garage door, I often pushed too far. The important part of this story is that it was this product which allowed me to finally send the demon spawned paint on my garage door to the pits of hell. This was after innumerable other product failed, to include strippers, sanders, heat guns, razor sharp scraping tools and other implements recommended to remove stubborn paint. I thought I would be defeated and forced to remove the wooden doors and replace them, but alas victory was mine. Superior product for the price point.

Good value for the money.
Pricewise, these are a very good deal. However, their quality isn't up to some other brands. They wear relatively quickly, leaving more dust to clean up. For the casual user they're quite adequate. Like many things in life though, it's a trade off.

They wear out fast, but there are a lot of them
They are ok. They do the job, but you are constantly changing disks because they burn up so fast. They are also thin, so on my grinder I had to double them up so that the nut would fully seat. On the plus side there are a lot of them, so you can have a fresh disk all the time. I go back and forth on whether I would buy again.
