I just learned about these polishers. They are so much better than using regular sanding discs or barrels. I highly recommend them. Its hard to believe that a flexible disc is as powerful as it is. Use the course and medium polishers with care,don't underestimate their power.
The last two polishers made my work shine quickly and beautifully!
They do wear down fairly quick, I suggest keeping extra on hand.

I have just started using these....they are perfect for my latest obsession (working with silverware) to buff out nicks and dents.

Glad I got the set so I can see what each one does. Very nice that you get 4 mandrels so you save time.
