The cable works as described, but contrary to Jonathon's review, I found it incompatible with the official Pi 7" touchscreen case. Perhaps he found a different case than I did? When I closed the case, it pressed on the rigid part of the cable connector, and broke the card slot case. That case is ridiculously flimsy, the electronic connection was not damaged, and I expect I can repair with glue. If the rigid part of the connector were slightly shorter, it would probably work for me. Of course, Simon C would like a longer narrow rigid portion. Oh well, I would love to see a variety of extenders, with case compatibility information.
