4 in Magnetic Copper Welding Backer is rated 3.2 out of 5 by 12.
Rated 5 out of 5 by from Strong Magnet The magnet on mine was really strong. Works great!

Rated 5 out of 5 by from Another Wonderful Tool These are made from 1/8" copper plates w/ good strong magnets imbedded in them. I had always kept a sheet of copper under the workbench to be cut and used as a welding backer when needed. These are much heavier, easier, reusable, faster and so much more convenient. An awesome investment !

Rated 5 out of 5 by from Powerfull magnets I purchased this thinking the magnets might not be that strong since they were small. I was very surprised. It works very well. The copper plate is also a lot thicker than I thought it would be.
