It works, and it's one heck of a clever idea.

That's the good news. The bad is that the execution is not
great. Everything is done with zip ties. The wiring harness
is mediocre, the sensors are mediocre. I had to replace the
wheel magnet with an old one that was larger and stronger.
The overall impression is a brilliant idea that needs some work
to get the details right.

I'd like to see the computer respond faster to input, but that's minor.

What I would suggest to the company is to replace the harness with something better (or sell just the wireless). The mounting bracket is
also cheap. The computer itself is large, I would like to be able to buy
a stem mount bracket.

Oh, the instructions were on this tiny booklet. They could stand to have the pictures
full page, and the instructions more detailed and complete.

I had to have the LBS install it since the original wire (for the cadence sensor) actually broke. Some of the zip ties were brittle so I think the box just got too warm at some point and time. It wa the first system that the shop did so it took them a while and I brought in my own trainer (KK Rock& Roll) Once everything got connect it was pretty responsive It does offer more features than the Sigma it i replaceing with temp/Altitude and HR.
