Query: Has its issues, but eventually did its job

I am pleased with the performance...once you're able to attach the tools. I found it not only difficult to get them in, but it took even more time to switch them out. Obviously mine has a small defect in the locking mechanism, but I was able to get it to work eventually. Also, some of the sanding bands are to big for the bit, so they slip off while filing. All and all once I was able to get a bit on it, it worked great for buffing and sanding.
