Impressive!
I use the Magene speed/cadence and Wahoo heart rate monitor with Cadence App. You can see the speed sensor literally taped to my Spinner front wheel. In the settings of Cadence you can adjust the wheel size for accuracy. I had a analog Cateye on my spin bike for years. The speed and cadence of the Magene sensors essentially mirrors what the Cateye readouts were. I will say the refresh rate is a little slow at times but very functional and accurate in my opinion. I like that there are no more wires on my bike and the functionality of using my phone for the monitor and storing the data from my workouts. If you choose to use Cadance App know this. When you add the sensors they will both show up side by side and you will think your done. You can select one sensor for each "add a sensor" so you must add them both again, select speed on one and cadance on the other and all is good. I find the Magene sensors to be a great value and I get accurate data on how I am performing in my workouts. In the images you will see the installation and the riding screen and the data output.

Buena conexión y transmiten datos correctos.
Lo primero que he de comentar es que antes de comprarlos tenía buenas referencias de este producto por compañeros de grupeta y tras cuatro meses de uso puedo decir que ciertamente es un buen producto. La colocación de los 2 sensores resultó sencilla y segura gracias a las bases de goma (una para la biela y otra para el centro del buje) que consiguen un buen apoyo, además las anillas de goma han logrado una buena sujeción. La configuración a sensor de cadencia ó velocidad es sumamente fácil ya que sólo hay que sacar la pila y volverla a introducir para que cambie de un modo a otro. La sincronización con mi ciclocomputador igpsport ha sido rápida. Su funcionamiento es bueno, al inicio tarda un par de segundos en dar señal, luego transmite datos correctos. El único problema que he tenido es que la pila de uno de ellos sólo me duró 20 km, por seguridad cambié las pilas de ambos y tras 4 meses no me ha ocurrido ninguna incidencia más. Conclusión: un buen producto con una relación calidad/precio satisfactoria.

Ótimo sensor
Instalei na bike de spinning, funcionou bem fixando perto do eixo, na roda não mediu direito. Usei abraçadeira de velcro e fixou perfeito, minha bike tem uma roda de 19kg. Já a entrega, comprei o produto que não informava que se tratava de uma compra internacional, Amazon deveria cuidar melhor disso, eu não teria comprado desse vendedor se tivesse a informação de compra do exterior.

Garminに問題なく使える
Garminのサイコンに問題なくペアリング出来ます。 アプリGarmin connectにはペアリング出来ませんが、逆に出来ない事で、センサーを付けたまま後輪やディレイラーの調整・メンテナンスでセンサーを付けた車輪を回しても走行距離を記録しないので良いです。 Garmin純正スピードセンサーは、ホイールを回すと、サイコンの電源が入ってなくても、〇〇km走りましたとガーミコネクトに表紙されストレスに感じてました。

Excellente précision, installation facile
Ce pack de deux capteurs remplit parfaitement sa fonction. Faciles à jumeler via Bluetooth ou ANT+, ils se synchronisent sans problème avec mon compteur GPS et mon application de suivi d’entraînement. La fixation est stable même sur terrain accidenté. Petit bémol : pas de guide d'installation papier, tout est en ligne.
