I set a couple of bikes up with these. Very simple to set up, programmable and reliable. I liked them so much I bought 5 for my own spare parts shelves and have installed in 2 of my bikes. Made by an XS specialist for his own bike they're not always available. He also makes good starter wheels that throw into the crank. The problem is that as a Euro sole trader production runs aren't that big, how reliable is future supply/support and post. But then, I'm not going to last another 100 years either and now is NOW.
Please tell more about the ignition it is listed not available there but perhaps comes some day
