They work great, as they are supposed to do. I've read a couple reviews that said "oh, they wear out quickly". Sometimes- that's the tradeoff. You're spinning a (knock-off) Scotch Brite pad at Sometimes upwards of 22,000 RPM. You want your workpiece to come out right, not worry about the 5cent disposable. In the end... the different textures work true, they quick change easily, and get your job done at an affordable price. Someone asked about 'ease of cleaning'. A couple times I have just given a quick shot of brake cleaner to remove some oily greasy gunk I got into on doing things like stubborn gasket removal. Give a blast, face your tool down, maybe into an old bucket, give a rip,and you're clean.

I'll be ordering more for my husband. He works on cars and this is by far the best deal on these. Works like a charm. He loves that they come in these different pairs. You have smooth ones and aggressive ones.

A lot of people complaining about the quality of these. Honestly for around $0.30 a piece they are and excellent value. They are generally only gonna be good for one use but for the price that’s what you would expect

they're all much harder than the 3m ones but that's not a bad thing. don't push too hard into the material, just let them do the work. have gone thru dozens and have not had one "launch" out of the holder or come apart prematurely yet.

Works like a charm. Love how easy they are to use. Pretty durable. They do not come loose while using.
