Got these pedals the same time as the KSC-70 Stand for my Roland FP-30 keyboard. The pedals only work with KSC-70 and when combined the make for a really neat, stylish and minimalist digital piano. The pedals provide a bit more stability for the stand and it feels quite sturdy when assembled. Assembly was easy, all you need is a screwdriver. The wood is only mdf/chipboard but seems decent enough all the same.
