I've owned several different brands of sustain pedals (M-Audio, Nord, Proel) and they are all big, bulky and quite reliable, so I had my doubts when I ordered the tiny FC-5. Wow, it was quite a surprise - VERY durable, fully metallic housing with a good rubber grip and an overall pleasing and reliable click of the switch. It effectively replaced all of my sustain pedals in a heartbeat.
