My recent experience with 2 made-in-China Sunex magnetic sockets is not good. I ordered them from Amazon and was hoping to receive the made-in-Taiwan versions, but received the made-in-China versions. The 1/4" socket (1/4" drive) has a magnet so deeply recessed it was useless at holding a sheet metal screw. And the magnet popped out of the socket on the first use with a hex bit. I returned it to Amazon. The 7/16" socket (3/8" drive) has a magnet that is substantially weaker than the identical diameter magnet in my made-in-Taiwan Sunex 11mm socket.
