I haven't used my Cobi unit since last year, but I did ride about 1250 miles with it. During the 5 months that I used it, the app crashed about 3 times which made me swap over to my intuvia display. I always kept the intuvia display with me at all times as a backup. The one bummer with my experience is the plastic they use on the mount is a very basic ABS plastic that is prone to stress fractures. The unit that I had ended up breaking the mounting rails off itself. If they haven't addressed the issue already, they should use some type of fiber reinforced plastic like the stock Bosch Intuvia mount to prevent this problem. One last thought was that the Cobi unit might interfere with lights that are mounted at the center of your handlebars. It will not work with my current Supernova m99 mounted to the bottom of the Bosch Intuvia bracket.
