Super sensors

Required a couple of sensors for speed and cadence so I could use my classic turbo trainer with cycling apps. I went for the Magene S3+ in the end as they were small enough to fit my rear hub. Was a little concerned they wouldn't work properly or they'd be inaccurate but I had nothing to worry about. I've tried these on both Bluetooth and ANT+ and they work perfectly. No messing around just wake them up and your app will pick them up through the chosen connection.I installed the Magene app to manage the devices and set the mode cadence or speed. That was straight forward. They seem to have also been shipped with the latest firmware.I've tried these with Rouvy and they work. I haven't cross checked the accuracy of the sensors yet but my cadence and speed seem to be on par to my road cycling with similar effort. I've also connected them to Bkool with no issues.We'll see how long they last or if there's any issues with them but it's too soon to tell. So far I'm really happy with the sensors and would recommend these. If you're looking for well priced, small, magnetless sensors then you've found them. Great value.

Worked fine on day 1 - compact - tidy

Was a little nervous after reading a few more negative reviews but after a 50 mile ride (dry) I’m happy with the connection and data to my head unit. Have used an additional cable tie and different bands to secure both cadence and speed sensor . Put the speed on the rear wheel hub and connection is continuous and stable ( I probably should have used front hub for a more direct signal though)

Great reliable product

This is my third purchase for another bike replacing the Garmin magnetic sensor. Lighter and simpler. Good reliable product. Remember to check what the se sensor is set to by the red or green led.

Reliable and constantly connected

Works brilliantly. Cannot fault it at all. Unlike the couple of reviews that are negative about the device and its compatibility with certain apps, it has been known for quite some time that a lot of apps are moving away from permitting third party devices work with them or require you to have a paid subscription to be able to do so, Strava one of these. So bearing this in mind blame the app developers and check before hand. That said I have Strava premium account so no loss for me and it works a treat.Set up, once the fiddly part has been done, using the supplied fixing kit, getting the sensor fitted to the back wheel and paired with my phone is straight forward just like their heart rate monitor that I also use which I can say has been absolutely spot on so far. Can't fault this process at all for either device. Simple as one two three.In use as speed or cadence sensing, I have found the sensor to be just as good as various other premium-priced devices that I have used in the passed. No loss of connections, no bad syncs, no errors at all from my experience so far. Switching between the two modes does require the fiddly part of unclipping from the rear hub and placing replacing the battery but that is nothing, most of the time its fitted and stays put but on some days I will fit the sensor to the crank arm for use on the bike trainer and use the cadence features. No issues with speed or cadence pickup. Given the fact it's on one unit and no magnetic counterpart switching between the two is an acceptable part of such dual usage. To get working you just need to power up your app and Bluetooth and rotate the crank or wheel and the pairing will be instantaneous.Definitely a good device for those looking for a cadence or speed sensor with good reliability but on a budget.

fails to maintain bluetooth connection

easy to install and initially connected to Garmin 820 Edge on my internal trainer however 2 days in the Bluetooth connection to the speed sensor is lost - tried forgetting the sensor and re connecting and now won't connect at all - disappointing results. connection to the cadence sensor has been ok and connects without a problem. may try another set after returning these as the price is very good.... if they work
