DC1702 15 Channel touchable LED Remote is the top of range of the remote control in my opinion. It's very high quality built and very solid. It can control up to total 15 curtain motors or Roller Blind tubular motors ( uni-directional ) separately. each channel can control 20 curtain motors or Roller Blind tubular motors to operate in the same time.
