While I understand why, it would be nice if this kit, which is specifically sold as a cadence kit, came with the computer set to have cadence on! Here is why...
Getting this mounted on the bike is a very straight forward process and the instructions walk you through the steps. But, imagine your frustration trying to get the cadence sensor to light up while installing on the bike (first few pages of the manual) when the setting to enable cadence is about 40 pages later. Even if there was a simple line, "Please make sure cadence is enabled before you test your bike installation, details on page X," that would have improved things. The manual does a nice job otherwise.
Once the unit is on the bike and you start riding, this bike computer really shines. There are a lot of settings that you can tweak to your hearts content. With auto start-stop, basically, you go out and ride. I like that I can see speed, distance, heart rate, and cadence all in one view. You have a bunch of choices for your view depending on what you like, and flipping through the views is just a single button during the ride.
Once you are back after the ride, it is very easy to review the workout data. Highly recommend and this would be a five-star rating if they managed to sell it with cadence enabled by default.
