Runn Smart Treadmill Sensor - Retrofit Smart Treadmill Sensor, Bluetooth & ANT+, Black

Works as intended and pairs well to android device. Used B7000 glue to help reflective tabs stay secured to treadmill track and have had no issues. This is a game changer to be able to use Zwift while running on the treadmill.

Easy to set up and worked immediately. Takes a few minutes to calibrate the speed of the treadmill with the Zwift run application. I found it gets around 90% accuracy. The problem with it is that it occasionally turns itself off in the middle of a run. You know it has happen because your Zwift Atavar will stand still while you are still running. Its a bit annoying having to slow the treadmill, jump off, turn the sensor on again, jump back on and get back up to speed. When its bad it may happen every 2Ks. Given I am old and only run 5Ks I try to think of it as a stop to have a drink.😅

Great product and very quick and easy to set up. Trouble free running on the treadmill with Zwift. A lot more accurate than a foot pod and trouble free fast connection. Long battery life with easy recharge.

I just got it and used it once so it's too soon to say if I'll have the issues some others did. I'll update this if I change my mind but so far so good. It connected as a foot pod to my Garmin vivoactive, but the Garmin started behaving badly with it connected (weird heart rate readings and inconsistent reporting of speed). Based on experience I suspect that's the Garmin and I have more troubleshooting to do there, but just reporting for anyone wanting that. It works great with the peloton app and other Bluetooth apps. so far using the stickers worked fine attached to the bumpy rubber treads of my curved manual treadmill. It did not seem to mind the speed not being steady like with a motor, and I'm just ignoring the incline stuff. Tracked pretty well with the reported treadmill speed and my own sense of exertion.

I don't write Amazon reviews. But this device is so lame I felt compelled to save others from frustration. This device did not work for me at all. I have a Commercial 1750 treadmill and followed the directions to the letter. It would not capture anything from my treadmill no matter how/where I mounted the device. Luckily, you can calibrate it for issues like this. Unfortunately, their software will not run on an Android device unless it's ancient. I have a Samsung S24 Ultra, which came out 2 years ago as of this writing, and that device is too new for their software to run. I reached out to support about it, but I didn't hear anything back from them. The build quality isn't great. It feels like a child's toy, made of the cheapest/flimsiest plastic. In my case it was a complete waste of money. I wouldn't recommend buying this device, especially if you're an android user. No idea if it's a better experience with iOS.
