Good value
These discs provide a mirror smooth finish off my Dewalt orbital sander. Great for an oil or "clear" finish. The backing on them is high quality and they stay on the sander pad very well. They don't last quite as long as the Norton 3X brand, but at this price, I'd rather have a fresh disc more frequently anyway.

Best Sandpaper for the Money
I've been using Norton Brand for years just because it is readily available locally. When it came time to stock up, Mirka was recommended, so I decided to give it a try, especially since a 50-pack costs $17, vs. $9 on a 10-pack of equivalent Norton Sandpaper.
After using the Mirka for a few weeks, there is no comparison. The Mirka last longer and the 320 grit leaves a smoother finish than any other 320 grit paper I've used. As I use up my Norton paper, I will be replacing it exclusively with Mirka H&L disks.

Leaves a Silky Finish
I have purchased every grit of Mirka sanding disks from Amazon, and I find them to be good quality. The price per disc works out to be a great value if you purchase them in packs of 50.
With the 320-grit, you get an amazing, silky finish on your wood surfaces. You can stop sanding at 220-grit, but if you take another step to 320, the wood really is beautiful to the touch! I use these discs all the time on cutting boards and table tops.
I used these disks on my Bosch random-orbit sander. The hook-and-loop backing is strong and holds on through rough sanding. The aluminum oxide sanding material lasts for a good amount of time. I have bought other brands of sanding discs that do last longer, but the Mirka discs definitely hold up well.
The discs are packaged in a sturdy box with a cover, which makes it easy to dispense them as needed. Also, having them stored in a box keeps them clean, which helps the hook-and-loop function. This actually helps out a lot in the shop. Other brands come wrapped in plastic, and you have to find a container for them, or let them sit on a shelf and get full of sawdust. I appreciate this extra touch.
The paper stock is somewhat thin, but this does not really affect their use. Since they are stored in a box, they stay flat. Other brands, which are stored in bags, get curled up on the edges.
Bottom line: these are good quality sanding discs that last for a good amount of time, are a good value for the money, and are packaged in a convenient way.
