Query: great product

I've had the Porter Cable for about a month. It's great. Easy to change the paper. Does the job. Good quality. I purchased a Ryobi 1/4 sheet sander and used it for less than 2 hours when it died - a piece of junk. I'm using the Porter Cable for small projects - toys and puzzles but have plans to use it for furniture and others tasks. Can't be more pleased with it.
