Works just as intended, not much to say in terms of functionality, it pairs well and records cadence accurately. It's also quite durable. I had the misfortune of getting into and accident and it withstood the bike falling onto the side of the crank where the sensor was on. Only complaint is that it's a little thick/bulky, but otherwise it's perfect.
Works well if you can find a bike it will fit on. It is too thick to fit on either of my current bikes, but would fit on a 2016 Trek, so I kept it. Be careful and make sure you have enough space in between the crank arm and chain stay.
This cadence sensor is too thick for modern applications with tight clearance. 2023 TREK Emonda SL7 with Ultegra crank, sensor will not clear the chainstay. Works only on frames with more cranks space next to the chainsstay.
