I have a TST 507 system and am very satisfied with it. I did not get the pass-thru sensors, opting for the standard sensors instead. The user replaceable batteries last about year, and only cost around $0.50 each. I previously had a TST 510 system with non-user replaceable batteries, and that one also worked well. When the sensors finally started failing at around 6 years, TST offered me a great deal on replacing it with the 507 system rather than having the 510 sensors updated. Super customer service!
