XOSS Bike Cadence & Speed Sensor - Wireless ANT+/Bluetooth 4.0 Bicycle Computer for Cycling Training, Fitness Tracking & Outdoor Adventures

Muy bueno pero la batería solo dura 4 díasLinked it up to the Wahoo! app and put it on the rear tire of my road bike in the trainer. Measured time and distance ok, but the battery died after 2 weeks. The manual stated 1000 hours of battery life, not so much.Have replaced the battery and linked it to the Garmin Instinct, works excellent at collecting speed on the stationary bike, will move it over to cadence when it's time to get the bike back on the road.EDIT: Put this away for a year or so because I wanted to use an old ANT speed sensor. Last week, switched my Zwift setup to an Apple TV. ATV doesn’t use ANT. Dropped a new battery in this. ZWIFT picked it up immediately. No problems.Picked this up to use with my new smart trainer, a Wahoo Kickr Snap, which surprisingly does not report cadence to Zwift. I had an older Garmin speed/cadence sensor hooked up, but it’s ANT+ only. Worked OK but for the price I picked up this XOSS to keep everything BT so the Zwift Companion app for iOS could run the show. Spent a bit of time setting this up because I assumed the indicator light would flash constant indicating the mode when the battery was installed. Only blinked once, hard to miss if your hand is covering the face. Anyway, after I figured it out, it was an EZ install on the crank arm. Tested it out on Wahoo’s app with the weekly calibration spin down. App found it with no issues. Fired up Zwift on my computer. Zwift found (rather the iOS companion app) the device with no problems. Did a ride around the Watopia course. I did feel the reported cadence was about 5 rpm higher than what I perceived using the old sensor. I may count my rpms next time, but for now good enough for my purposes.NOTE: for those who gave this a negative review, because you you expect it to show in your iOS BT device list, it doesn’t . It’s designed to work only with apps that support this flavor of BTXoss es una marca de excelente equilibrio entre precio y calidad, ya tenía el sensor de frecuencia cardiaca y es muy preciso y facil de instalar, igual estos sensores. Estoy muy satisfecho con mi compra.Can't directly use as a speed sensor on an Android phone. You have to use a compatible app (I'm using Wahoo) to connect to it. Android's Bluetooth see's it and will try to connect but despite never asking for a password it will say the password is wrong. Wahoo connects to it just fine.I can't vouch for it's accuracy vs GPS or another speed source as I have it on the axle of a stationary bicycle but the effort vs speed seems accurate.Worth the money IMO and don't listen to the knucklehead saying it doesn't work, it does; you just have to find a compatible app. Thinking of buying another to get the cadence from the foot/leg speed as well.I use one for speed and the other for cadence. The cadence senor needs a new battery almost every month. I really need it because I use the workouts and I get feed back and coaching on my cadence. The speed sensor lasts around six months. Heart rate monitor more. Is this normal?I like it but sometimes don’t work with the device XOSS G+. I need to re read the instructions.They send it to Colombia, in a regular time (10 days)I purchased the two sensors, one for speed and one for cadence. I have installed them on my hybrid bike, mounted on an indoor trainer. They were easy to install, connected very quickly and seem to be working as planned. I will update as I use them. Just did my first ride with them.I bought this sensor to pair with my Polar Grit X watch that I started to use as a GPS computer. This sensor paired easily to the Grit X and now I'm able to add the cadance to the display where I can see it while riding. This sensor was a good price compared to others and works really well. Some reviews mention this sensor can't be turned off and drains the battery. I verified that the sensor turns itself off after some time of inactivity and turns on with a couple of rotations of the crank.Ok, the product is small, works fine and has the right options to easily install on your pedals, but…..The thing does not turn off but you have to take it off your pedals (hard to do when your hands are sweaty) and take the batterie out for it to stop. Only to have to reinstall when you need to use it again the next day. Be careful because once the battery is reinstalled, it might be on speed or cadence. If the wrong one, you’ll need to take it out again. What a complete pain in the a…..I’m not engineer but an off switch or that it turns off when not in use would be a simple solution.Very small compact sensor which fits on my left side crank comfortable with the supplied rubber bands. It links with my cycle computer after a few revolutions. It does switch off if idle for a few moments, but comes alive rapifly. There is a 4/5 second delay between the cadence and the computer. All in all happy except for the price which is only 22 USD in US but 35 USD equivalent here in India.These are awesome sensors. You need one for speed and one for cadence. I am using Wahoo app to track speed and cadence and they paired instantly inside app as you don’t pair to phones Bluetooth. Would buy again in a second. I checked the cadence and speed compared to my spin bikes default monitor and the cadence was bang on and speed was off by about 15%. This is easily adjusted inside app with wheel size selection so mounting anywhere on where is doable.Well, i used it 3 times on my indoor trainer, and it broke on 3rd use. Seemed to be working ok, but unfortunately it is really flimsy, and the plastic tab where the elastic attaches. Unusable now after 3 uses.
