We have the TST 507 non flow thru due to problems I heard that the flow thru have. It only takes a few seconds to remove the sensor with the tool to add air. The TPMS has been great for about 5k mi towing. Would recommend getting sensors for spare tires on TV and towed unit and think sensors for airbags is overkill. TST 507 can handle 22 tires if needed.
The reason I purchased them was because of the flow through capability. Why purchase something only to have to come up with a work-around. Not only that, but due to the design, one of them started leaking air out of the body on me. TST replaced it under warranty, but the warranty is only two years. When others offer a lifetime warranty, it just doesn't make sense to deal with a flawed design.
