Plugged it into my Peavey Envoy, works as the Peavey manual says it should: one switch turns the volume boost on and off, the other selects the distorted or clean channel, without a popping sound, it's perfectly silent electronically.
However the hollow housing acts as a small resonant box, so the mechanical sound of the steel switches is enhanced. I find it a bit annoying, so I cut sponges in pieces, and stuffed them inside the housing to dampen the clicking sound, and it works.
When I opened it, I saw clean and full soldering; plus, the copper wires are not too thin. There was a bit of aluminum dust but I brushed it away. The housing is rather thick metal, and the side panels are tough plastic. The whole thing is rugged against shocks and the pressure of the player's weight.
The cable is okay but its rubber is not stiff and thick as a good guitar cable like my Klotz, so I give it only 4 stars. The jack locks firmly onto the amp's rear panel. The other end of the cable is crimped on the stompbox's panel, the arrangement looks quite solid, you can't budge it if you pull it.
The bottom has two rubber pads that don't wear out easily, and grip pretty well. An anti-scratch paint rounds up the thing. I don't travel with it but the footswitch looks like it should last long even if you do.
