Review on Efficient SATINIOR Computer Organizers with Mounting Diameter for Enhanced Desk Organization by Daniel Ogbebor

Overall they work good, but the hole in the cover is so small that there isn't much room with a regular sized power cord. The only way to use it was to just remove the cap and treat it like a big round socket. I've tried enlarging the hole in the lid, but it's almost impossible to get it right. It would also be nice if they were in a smaller version so you could insert them into opposite sides of a cabinet opening (I've used them for cables through vertical dividers where both sides are visible). Or, even better, a reversible version where the two sides snap into a hole.
