This was easy enough to fit, as simple as any temple stuff with their teeny tiny screws. Once it's on it feels solid. Having an on/off switch is great, and all I can say about the noise filter is that everything is still noise-free so I guess it works!
Because of the placement of the module slots, the IEC cable sits slightly off the ground and already our vocalist stepped on it during a gig and unplugged the board (luckily between songs!), so wedging a piece of wood under the cable might be a good idea? It's the only area where it feels vulnerable.
Also it's expensive, obviously, but I don't regret buying it so overall it's just about worth the money for the convenience.
