Review on 🚴 Wireless Bike Computer - Sigma BC 9.16 ATS by Ron Collins

I bought it in June 2018. I don't drive often, I only drive in the summer and early fall. The problem is in the sensor. I spent a lot of time fiddling with the battery thinking that was the problem, but after testing a battery I was using and then a new one, I found that it wasn't the battery. Unscrewing the battery cover is not possible, but even after tightening it and making sure the sensor is aligned and close to the magnet on the spoke, I concluded that the sensor is defective. I will not buy a $25 replacement sensor, I will just buy a different brand bike computer. Has worked well so far but I expect it to last 2+ years.
