Review on Efficient SATINIOR Computer Organizers with Mounting Diameter for Enhanced Desk Organization by Joel Young

They were delivered on time and well packaged. The plastic they are made of seems durable and expensive. They fit perfectly in the hole I made with my 1.5 inch hole saw. (Tip for drilling a hole: start the hole on one side and turn the workpiece over, insert the center drill into the hole that came out of the first cut and drill all the way to the end). This avoids a rough hole on both sides. A word of caution about the 1.5" hole, some larger plugs will not fit through the hole so be sure to measure the size of the end of the plug before choosing a sleeve size.
