“I found this sander to be a nice upgrade from my older one. Some reviews were mentioning when tightening down the tables you needed to compensate so it would end up in the angle one wants. This was happening only for the belt table on this unit. Easy remedy, I just cleaned the surfaces and (cut from a 5" disc) applied paper backed PSA 150#. Locks right in place now. Additionally, tracking works fine, very low noise level, .003 face runout on disc, solid operation and nice to have dust ports.”
