Very handy! It looks very useful, and a nicer alternative than just the strip one sold by CTRE.

Instead of putting 4 boards on each 5cm x 5cm PCB for overseas manufacture, one could use OshPark in the US; they have no minimum size and ship decently fast (1.5 weeks to arrival after ordering). They charge $5 per square inch for 3 boards, so a 4 square inch board (5cm x 5cm) is only $20 for 3. So you get 12 PCBs for $20, which is not bad considering the lower cost. Or you can order fewer PCBs by splitting up the 5cm x 5cm board.
