Not much to say about this connector outside of the fact that it does exactly what you'd expect. The jack quality on both ends is nice and sturdy; no loose tips or offset shafts. The middle section is made of metal and the texture is similar to that of a regular guitar knob.
The only thing worth being mindful of is that the two pedals that this will be connected to need to be even in height. If they're not, or if the surface beneath them is slanted, one of the pedals will be tilted. Over time this would likely weaken the jack on the tilted side, reducing the audio quality or outright not functioning if the offset is dramatic enough.
All in all, you can't really go wrong with this connector. If you're looking to efficiently pack a bunch of pedals together without having to deal with daisy-chain wiring, this is perfect. If there is any offset to the jack inputs, or the size of the pedals, then maybe look at atypical patch cables instead.
