I bought the TST flow thru system last year...was very pleased with it and getting ready to put them back on for their 2nd year...I removed them during winter and removed the batteries, no need having them on during 5 months of winter running batteries down on the driveway....did not experience air pressure loss.....hoping to get 2nd year off the batteries.....Customer service with this company is awesome....I bought a 6 unit set, put 4 on the 5th wheel and 1 on the 5th wheel spare, and then traded the 6th unit back to the company for the repeater to boost the signal....can't say they'll do it for just anyone but the guy I spoke with, who made the exchange, even shipped the repeater to our campground so we would be "road ready" immediately......that's called customer service!!!!
