This sander WILL fail to hold paper with in 3 to 5 months with medium use. Mine was not defective it is flawed in design. The sheetlock system is only slightly faster and not worth the trouble of failure. The horrible thing is if you want to just keep replacing the assembly you cant. Bosch discontinued it along with the bottom pad assembly. The guys that reviewed this thing well have only had it a short while. All the bad reviews have used it for a few months. Go with another brand with the basic sheet holding design, its proven.-Mark
