Recently bought the Astro magnetic spark plug socket set 94404.
Finally had a chance to use them (well, really only one size

) yesterday.
They work about 9247%

better than rubber-insert spark plug sockets (all that I previously had used).
Nice polished chrome plating, partial swivel connection to the permanently attached extension (can be disassembled if need be by removing a set screw), some knurling on both the socket OD and the extension shaft for finger grip and spinning by hand, nice strong magnet that holds onto the spark plug nicely.
With spark plugs recessed into the heads (sometimes a LOT), it is SO nice to not have to worry about the socket losing its 'grip' to the spark plug or an extension pulling out of the socket.
So, a BIG

to Astro for these. They are NICE. Nice to look at, nice to hold, and nice to use. Made the job go nice and smooth with no issues with/from the tool. Highly recommended.
Also used my Astro 3/8" nano ratchet 93808 for this job, short handle version. Again, a quality tool. The attachment from the tool to the extension held on great and released when I pushed the release button just like it should, the polished chrome is nice to look at and to use (nice and smooth on the hands), short handle was plenty of torque for working on spark plugs, the ratchet mechanism was smooth and worked with no issues, the reversing lever was right where my thumb could reach it to easily switch from remove to install to remove to install, the 'nano' size was a bit lighter and easier to maneuver around than a 'full size' 3/8" drive ratchet.
So, a quick shout-out to Astro for making quality tools that make the job/task go more smoothly with no tool-related drama or issues.
I said it before but I'll say it again, Astro is on the top of my list of tool choices.
