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

The computer itself can be a good work tool. I've had mine for 19 days now and it seems accurate. My problem is the mount. The plastic of the holder is very thin. It was 28 degrees Fahrenheit on first use. Breaks off before I've moved a leg. I thought it burst because of the cold. I then attached the strut to the bracket with epoxy so that when the strut came loose the whole side would be there. Potholes. I need to find another type of computer that can keep up. It can serve well on an indoor exercise bike.
