Plus points:
+ Beautiful, high-quality design (fits perfectly with the new bike)
+ Extremely easy mounting: is fully assembled within 3 minutes without any tools.
+ Display can be very well read and has a pinch even a light!
+ Operation is very simple and easy to understand
+ The computer can be removed with a very simple movement of the holder / fitted
+ Works for me with LED lamp (B & M Lumotec Cyo R) and hub dynamo (DH-3N72 Shimano) absolutely reliable, even though the transmitter is mounted right next to the cable
+ Has all the features that I can use (even temperature) and more
+ The price / performance ratio in my opinion is unrivaled good
The only small criticism is the manual. That's a bit confusing and explains some features only very meager. At the end anyway but you get everything out and if you have ever tried everything, you never need the manual probably eh again.
ADDENDUM (09.02.2012):
After approximately 1,200 kilometers and nearly a year, the battery for the first time is now empty in the speedometer. The transmitter goes in.
Otherwise, I'm still very happy with the BC. He also does the actual temperatures of -10 ° C still uncomplaining his service.
ADDENDUM (06/05/2013):
Meanwhile the odometer indicates 2600 km. It's still the second battery in it (which seems to last longer than the originals) and everything still works perfectly and without a single failure. Unfortunately, I now have a scratch on the screen, because I once had the bike computer along with a keychain in the host bag.
