  1. G***s

    looks great, connected to my Bryton Rider 15 ok, but slow to wake up when you ride. used for cadence in this case. great value.

  2. T***n

    The product is excellent. It has Bluetooth so you can connect it to your iPhone or android via bunch of applications. It can either measure milage or cadence depending on how you set it up. It is simple to use. Hope battery lasts as they suggested

  3. S***e

    Fast delivery, good dealer.

  4. V***v

    Good packaging and a very quick shipping. Highly recommended store. Got it paired as a cadence sensor with Garmin FR 945 in a snap. See a quick cadence test ride screenshot from Garmin Connect attached. Visually the sensor and mount and humidity insulation does not seem as solid as Garmin sensors but it is really a fraction of the cost comparing to Garmin. I am using Magene’s heart-rate chest strap for about 6 weeks, no issues whatsoever. Very nice product line at a very good price. So if you don’t want to swallow the Garmin’s sensor price these once are a perfect alternative.

  5. F***r

    Product like in description. Not tested yet.

  6. Customer

    Fast shipping, packing the post treatment. Great communication with store, forehead and working.

  7. A***k

    It came in a month, even in the apocalypse. It works right.

  8. T***o

    Very good!!!! Got everything right, 20 days to arrive

  9. E***

    Good product, I delay 8 weeks to arrive but good product

  10. A***s

    Very fast shipping to Spain. Just like the description. Good nice and cheap. Connected to my Garmin Edge explorer. Super small and barely weighs. Highly recommended.

  11. J***s

    Perfect fast shipping without bike riding and checking connection. I’ll do it this afternoon.

  12. J***o

    Fast shipping and works perfectly. I recommend it.

  13. S***l

    Shipping in time, fast pairing with garmin 520 and fenix 5s. Good store

  14. F***y

    It’s perfect! I received it in just over 2 weeks. It works perfectly with my IGPSport! Thank you

  15. E***k

    Came, put, works. Garmin 935 clung to the clock without questions. But the iPhone was connected, but the sensors can be seen only in the branded application, and not in the list of Bluetooth devices. Happy with the sensors. Done nicely, about the accuracy of the readings I will not say anything, use on the home machine, connected the sensors to Zwift via ANT +

  16. V***a

    It took me 1 month to get here because of the virus. I have connected it to a Garmin 820 to the first and it has worked properly, very easy to use.

  17. V***o

    Despite the alarm state I arrive before A month. Great product, works perfectly. It’s the second I buy and great both of you.

  18. E***i

    I received the goods with the package completely soaked

  19. I***N

    He arrived in Yekaterinburg about a month, everything was kept, until he appeared in the post office. The product is pleased, besides that I was put instead of two sensors, only 1 cadence.

  20. Customer

    Sensors arrived in 31 days to The Netherlands and were exactly as described. Sensors simultaneously broadcast Ant+ and Bluetooth signals. Confirmed working on Garmin Edge 820, Wahoo Element Bolt and Wahoo Fitness app.

  21. K***s

    Just what is described. Good quality

  22. A***a

    Excellent quality, fast shipping to Chile. Totally recommended!

  23. R***e

    Fast shipping, easily connected by ant +, worked perfect

  24. K***y

    The sensor works well. I recommend it, but be careful. If you want the speed and Cadence use together, you need buy two pcs

  25. M***a

    Excellent product, well packed, arrived fast and has been tested, all working perfectly. Thank you.

  26. A***o

    Very good product. Arrived very fast. Very good, fast shipping

  28. D***o

    Great product, delivery fast, yet not tested but the lights are lighting normally.

  29. J***a

    Excelent produt and quality. I will buy more one. Great store. I recomended.

  30. M***a

    Quite fast shipping, works fine, only the battery was discharged, realised that during first ride when sensor was constantly disconecting and changing from cadence to speed 🙂 Anyhow, far cheaper than garmin/wahoo, when comparing to Tacx flux trainer data – also pretty accurate.

  31. S***v

    Everything works. Mode switching occurs by disabling and connecting the battery. Attach photo tip for road bike wheel diameter in mm for speed sensor. My wheel radius = 2105mm.

  32. B***r

    Very satisfied. Thanks to the store.

  33. C***z

    İt took 2 months to arrive in Turkey although product is exactly how it’s described.

    Very good sensor. I use with Garmin 935, connects instantly, I use as cadence sensor. Very fast shipping. I am very pleased, recommend.

  36. D***i

    It’s fine. The sensor works both in cadence mode and in speed measurement. Paired with Garmin 520 edge without problems.

  37. A***a

    Everything is fast, you just have to connect. Thanks to the store;)
