Just set it up, it took a little while, maybe 30 mins, haven't figured out how to attach the urban style kit yet but thats a minor detail. The included manual design in minimalistic as is the in app tour. I got both the mount case for my phone and the universal holder but I don't think I could ever use the mount case, needs more design effort if you ask me. Once you put the phone in it, you can only charge it via the Cobi as there is no charging input, it also makes the phone much longer, so I'm just going to use a regular phone case and the universal holder. The included manual refers to a battery that it says you need to install, I did not get a separate battery, but I think its already installed and screwed in, either way the instructions are unclear about that too.
I have not used the app much yet, it looks nice but in a effort to be simple & intuitive, it actually is not that obvious how to do simple things like turn down the light. My guess is I will get used to it. Leading the bike to someone so they can it try out seams unworkable, the Bosch display easer to quickly understand. I really like the cafe lock although I wish it was louder (maybe it has hidden setting?) and the map app is nice too, not as good as google with their bike path overlay but the choise of routes is well thought out .
Looking forward to trying it out tomarrow
