I received the brushes and they met my expectations.

Why brass? These brass bristles are fairy soft and can clean up delicate battery terminals on vintage equipment. Brass is less likely to tear into plastic when you slip. I really like that this came in a bag of ten. You can go through these fast.

Worked as well as some name-brand brushes Ive used, and far less expensive.

The price is fantastic. A Dremel brush is more expensive, but it may be worth it because these dont last at all. Wear goggles! The wire bristles do fly out in rotation or when they break.

Showed up on time, look as advertised. Do NOT run these on high speed, but LOW speed. They will span out and fray, and shoot crap into your eyes and face on high speed dremel. Live and learn, use on LOW speed or they will HURT you and those around you, as well mess up what you are working on. Remember, they are garbage but work, and high speed will spin them out and become micro fiber metal darts to your eyes, face, hands, people, things, etc.

These are cheap and you get what you pay for. Compared to the same in a Dremel brand, at a much higher price, they have a very short life. Single use at most/best. The bristles roll over very quickly and become useless.

Good for basic metal polishing

These brushes are ok. Had to put on safety glasses very shortly after starting a project due to wires coming apart and flying everywhere.

They work well for my Dremel tool.

These worked great w/ the Simichrome polishing compound. It made my job much easier with less effort and even faster than last time! These didnt wear out like some of the natural bristle ones last time I had to polish something that was brass. I could apply more pressure and they didnt flare out and wear prematurely. Very durable material - love them! :D
