Query: Waste of money

The belt seems to look like it will outlast the sandpaper type. Absolutely no information on installing the new belt big question use the guide blocks or not I left them off seems to track just fine. Now the big question how well does it work ? Not to good work pieces totally slip the surface is more like nylon than rubber (if your familiar with rubber roofing pretty much the same.) just way to slick. I'm hoping in time some of the slickness will wear down then it might grip. I think for $100 with shipping it's a waste of money. If you do a web search there is a place that sells the sandpaper feed belts for $25.40 . Don't know if I can post the web site this might help search "Sanding Stinks but Our Sandpaper Rocks! "
