This thing made changing my 2011 4Runner spark plugs possible. Plugs are now sunk into a deep well. The magnetism enabled me to pull out the old plugs, and to insert the new plugs without risk of dropping them and changing the gap. It gripped my socket extension tightly. Other solutions I saw had electric tape holding a socket to the extension. Not needed here. Very happy with my purchase. It is well worth the price, even if I only use it every 100K miles.
