### ⭐⭐⭐⭐⭐ Best I have ever used.
*by R***W on August 31, 2025*

Every now and again I'll come across a product here on amazon that people are raving about and it will just be a bunch of hype but in this case the hype is 100% genuine. The are hands down the best flap discs I have ever used even beating discs I paid 2x the money for. When I used these to remove 9 layers of paint from some metal parts to refinish them, I could not believe my eyes on how quickly this stripped it down to bare metal. I had to put in so little effort that I didn't even drain a dinky 4Ah M18 Milwaukee battery doing all the pieces. I am extremely pleased with this product and sad that I hadn't heard of this brand before. If you are looking for something that works well, is fast, fits well and is durable look no further this it's the best you can get.
