Review: 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.
Review: 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.
