I love these flat FC5 sustain pedals.  They are much more durable the standard pedals.  Although I still have an original Yamaha pedal that I purchased back in 2002 and it still works perfectly till this day, I'm a little more partial to this one now.  I've been using this pedal for 2 years now and I haven't had ANY problems with it.  I bought this one to keep in my laptop gig bag, in case of a faulty pedal when I do gigs out.
