Since I'm a dealer for Pressure Pro, I have inquired as to their availability of an up graded sensor to allow the user to change the batteries. I have not heard back from them yet and will report when I get an answer.
In the mean time, I'm going to order a set from TST and do a simple comparison of the two systems.
