Review on Monitoring Universal Waterproof Real Time Temperature by Conrad Greene

I've only been using it for a few days, it works fine but there are two complaints.1. The instructions are limited in that they don't tell you how to move between the keys to program the hardware. Articles are also identified in the brochure by alphabetical indices - e.g. B. A, B, C, etc., but the monitor shows numeric values - z are very confusing. I have to teach myself by trial and error.2. Two sensors were mislabeled - front left and front right. So I had to swap these sensors. Hopefully the system will last me at least a few years.
