somewhat ambivalent

However:
- I had to put from right to left, so that there will receive the speedometer on the handlebar. Apparently the distance is usually too big (my bike is also quite large ~ 65cm frame)
- When the battery becomes low, there is no transmission. The speedometer indicates something, the sensor is to be green, "I've noticed the magnetic" signal, but the speedometer receives nothing. Then you have to change the battery. And that feeling quite often.

If it all were wired, I would prefer.
