Once installed it's sturdy and functional.
Installation was fine except the writing of the actual socket.
They use Allen screws ( fine, just different). I had to loosen the socket from housing to access them ( also fine).
However, when tightening the lugs it was apparent the threads were not chased, or maybe just not formed. It was extremely difficult to thread them on order to clamp the wire.
I backed off one grub screw and immediate regretted it. The screw was captive and wouldn't start threading. Fixing this one screw took an extra 45 minutes, basically doubling the install time. If the terminal lugs were simply threaded before being sent this would be a 5 star review.
Also, tip while installing, see the photo below, remove the cover plate, flip it out towards you, re-secure ( upside down), then thread and install your wire. This let's you get the right strip length and bend on the wires for installation.
