Works well with my Garmin Edge 540. There is a little lag time between increasing cadence and the read out. Doesn’t matter to me since I just want to see my average cadence. Has helped to improve my spin.

I already had app. Have bike computer thing. Both work well. Of course I never compared speed reading to any thing to check accuracy.

All of the Bluetooth cadence sensors I've used perform the basic function fine. This one wins on 1) price 2) mounting (standardized therefore replaceable elastic fixture) 3) battery replacement that doesn't require a coin! I can't emphasize that enough. With the coin-as-tool setup ... Is it designed for 100 yen? A quarter? Some other worthless currency that I don't possess? I always chew those coin slots up. This just has a little tab you can push with a fingernail. Beautiful! Consign coin-as-tool to the scrap heap of paperless history. Get this.

I use it with my other COOSPO, bluetooth devices, HR monitor, Cadence, and now Speed. I have had no problem connecting all three at the same time to my Wahoo iPhone app.

I recently got the Peloton app and decided to try cycling with my cheapie exercise bike. I realized I wanted a cadence tracker to be more accurate with their work outs instead of guessing. This one works perfect. It's easy to hook up to the bike, and pair with Peloton app while using a tablet or phone. If I'm using the tv, then I open the CoospoRide app on my phone to track the cadence. It seems to be pretty accurate as to how fast and slow I'm pedaling. This was one of the cheaper priced ones I found. Definitely worth it.

The sensor started dropping out after a couple of rides until it was not working more than it was working. They may have shipped a bad battery, but before I could replace the battery the sensor fell off on the road somewhere.

Mine works well. I was able to pair it with the Cyclemeter app and with my Garmin Edge 840.

If you want to use this sensor for applications where you’d connect to it with Bluetooth, this is a good option. If you’re going to use ANT+, I can’t recommend it based upon what I’m seeing (at least at software version V1.1.7).When I originally got this sensor I paired it with my Garmin 830 using ANT+. When I did that, I noticed that the information provided to the Garmin was limited, including a lack of battery state.For comparison, I reconnected the sensor to my Garmin using the Bluetooth Low Energy (BLE) connection. Using BLE, the information screen shows battery state, that it is running software version V1.1.7, and that its Model # is 2023-07-05.I have an iPhone. I downloaded their app, CoospoRide. I guess it’s okay for getting info from the sensor. But, I doubt I’d worry about using it except if I was diagnosing the sensors themselves. Fundamentally, I don’t know that I should need another app just to manage sensors.This review will probably come through for both the speed sensor and the cadence sensor. For the speed sensor, if you have a choice in your application, use BLE rather than ANT+. When I originally got this sensor I paired it with my Garmin 830 using ANT+. I noted when riding that the sensor tended to jump from one speed to another. At 30 km/h (19 mph), the sensor would often jump in steps of about 0.6 km/h (0.4 mph). In open terrain, the speed information given by the GPS alone is better. While bike commuting, the jumps in speed are okay. But, if you’re trying to hold a consistent speed (like when you’re pulling on the front of a pace line during a group ride), this is more than annoying.
