Works as advertised - good quality, nice heft. I use it with my fine wire plugs, no issues at all.

This deep socket did the trick when others failed to have enough depth to fit securely. The magnetic qualities were welcome and made the tool feel much more secure when working with the fragile and expensive plugs.

After 25 years of changing Champion plugs with a standard deep well socket, I was surprised when the same didnât work with Tempest plugs. Their design requires an extra deep well which this socket has. The magnet securely holds the plug while you get it lined up and the thin wall makes it easy to get into tight places. Itâs a bit expensive, but worth every penny.

High quality. Expensive for a socket, but the magnet is good and strong. If the magnet keeps me from dropping just one expensive plug, then it pays for itself. I like it so far.

Its a good socket. I wondered if the magnetic feature was going to hold the plugs properly. The magnet seems to do a good job of keeping the plug secure in the socket during removal and installation. Ive payed more for specialty sockets and Ive payed less. So, the price is what it is.

This is a quality thin walled socket for spark plug removal and insertion as the magnetic feature helps guard against accidentally dropping a plug which is important with any plug--especially the expensive fine wire plugs.

Quality appears good. Used to replace six tempest UREM40E plugs and the fit was good. I did like the magnet that holds the plug over rubber method.

Great socket. The magnet is a definite improvement over the old rubber grommet.
