Review on JGRZF Bike Computer: Wireless Speedometer and Odometer with Backlight, Waterproof LCD Display – Ideal for Outdoor Cycling and Fitness (Wireless Computer) by Athenasby Whitney

I chose this one because it has a wired sensor. For me, wireless would likely decrease battery life, and I didn't want to deal with line-of-sight issues and interference. The temperature can be set in both F and C, which is not mentioned in the description. Been riding the bike for about 2 months now and the battery is still fine. Take it on 3 rides, each was for about 2 hours. The only thing I wish the backlight was blue instead of green.
