I could’ve probably helped you out with a few those ahead of time. But I took break from the internet while I was on vacation. Well, they don’t exactly like you have phone out at tables either haha. Sorry about that!
The Wago’s do seem a little cheesy from that respect, but they’re much nicer than wire nuts and much easier than terminal strips. If you grab some of those cable tie mounts we talked about either, you should be able to tie them up nicely and inconspicuously.
$190 is pretty steep, but not so bad when you consider the options. If you were to hang individually, you’d get tired of the mess of wiring quickly. If you sourced the aluminum to build your own frame, it would probably be $100. By the time you consider all the hardware and labor, probably not saving much. Especially when you consider the amount of adjustability you have with that particular frame.
Either way, it looks like you did a good job of getting it together! Assuming they sent something like 18 awg solid with the kit? It was kind of a hassle for me to find locally, so maybe be ready for that. Amazon had some reasonably priced stuff if you run into any issues there.
