Good alternative with weaknesses

After 12 years Sigma I wanted to try something else.
The O-Synce MINIfree is really a fancy bike computer, but it does not work with the hub dynamo + LED light.
Too bad that there is no mention about it was in the guide or even better you will be informed before purchasing.

What I also found for not very nice that it is very very difficult designed, if you want to mount the speedometer cross.
Also, I am no friend of fastening with cable ties.
The lack of lighting have then prompted me to send him back to me and again to buy a Sigma.
