Review on Schwinn 11-Function Wireless Cycling Computer by Jay Kenville

Very poor instructions, very difficult to read, very very small writing. After the installation I still had to play around with the sensor. I have another Schwinn wireless on a different bike and it works great. However, this one is not. I set the time but still haven't figured out the charts. What is the problem with verbally explaining the direction? If I hadn't installed other wired and wireless devices I would have been completely disappointed. In addition, it is difficult to operate while driving. Buy something else.
