Joe, I too am leaning toward the Trikor because I want to be able to fill the tire without removing the sensor. I had some of the little chrome sensors that flash when the air gets low, and the only problem I had with them was they would leak sometimes when I didn't tighten them enough after removing them to fill a tire. I applied a minute amount of pipe dope to the threads and didn't have any more problems. My point being that every time you take any of the sensors off you take a chance of damaging the seals and/or causing a leak.
