I've had the TST system with flow-through stems now for two years. I have had more issues with them than I care to think.
Several of the stems worked intermittently and were sent back under warranty. The flow through stems are very hard to fill. Can take a long time. Installation can be tricky. You have to screw the stems on "just until the air stops leaking out the threads". If you over tighten then, they won't work.
Another issue that disturbs me more than anything was me hitting a curb and knocking off the complete valve stem. Everything broke off and fell to the ground. Not knowing that I had hit the curb, I kept driving. The monitor never went off! I noticed a handling issue and pulled to the side of the road and discovered a flat tire. The monitor never indicated a loss of pressure to the tire. TST's answer to this was that it only reads an active monitor. A lost sensor won't tell the monitor that it is gone.
Their sensors also do not play well with valve stem extenders. You may need to replace your extenders with valve stems that will allow proper fitment.
