I use this product for the magnetization of a plus driver. Other inexpensive goods are attached to the driver and put in the tool box, and when other tools are pulled out, the other tools come in contact with the magnet and come out with the driver. The magnet has a strong magnetic force at the side, but the magnetic force of the driver is not very strong. On that point, this magnetizer is very good because it has sufficient magnetic force. Also, it is very good, because no other tools stick to the side at all.
