I use this expression pedal with my Zoom B3, which I would highly recommend to bass players. I have not used the expression pedal much, but it is certainly of good quality, it is made of metals and plastics but I am fairly certain it is up to gigging regularly. That said, it probably is less durable that say, a metal stomp box from the likes of Boss. Nevertheless, good product, does what it's supposed to do and is relatively inexpensive. What more can we really ask for?
