Review on Wahoo Fitness TICKR Monitor Stealth by Joshua Paulson

Just got a new ticker (white). According to the manual, the firmware should be updated. I tried, the application has an error that the update cannot be completed. After several attempts, the progress bar on the update screen went to the end, but it still didn't show that the update was complete. Closed the app and reinstalled, this time it found the latest firmware and didn't throw any errors and was able to see the sensor normally. But the heart rate in the Wahoo app shows zero for a minute and then no longer detects a signal from tickr. Also tried reading on my Wahoo Roam, same problem - could detect the sensor but couldn't read the heart rate. Tried the "fix" on the Wahoo website by flipping the battery for 3 seconds to reset it. It did not work. I also tested with a new battery, but that's no problem. Start the return process, too bad I need a sensor for an upcoming bike ride. I've been using the original version for a year now when it started failing. In my limited experience, this product is not very reliable.
