Review title: PLASTIC RING PROBLEM
Product review: The sander is a fine product, with the exception of the "controlled finish system". This system uses a plastic ring which wears out rather quickly. When I bought the sander another ring was supplied, which I've misplaced. I am now stuck with a sander that works improperly, shoots shards of this plastic ring out, and I cannot seem to get a new ring for it. Lifespan was 1 month of heavy use. My boss has a porter-cable and it doesn't have this system. It seems to work well without and has had a year of daily use.
