Query: Outstanding!!!!

I bought this machine because I have a 2 and a 3 yr old and other DVD repair products weren't able to remove the scratches they caused. This one works!! Although it is a little pricey, I believe it has already paid for itself. Some tips: work in batches when repairing because of the multiple steps and although it doesn't say to, you should use the cleaning step as the last step to remove any excess wax - don't hand clean! Also, the polishing pads are pretty sticky, I only took off a small piece of the backing, otherwise the polishing pads tear when removing them from the mounting plates.
