I have the Tire Minder brand. Alarm has gone off 3 times. 1st 2 were when I took a right hand turn from a stop too fast. The rim bead was momentarily broken and air leaked. The monitor shut off once I was going straight (I take turns much slower now). The last time it was an alarm showing an air leak as I was pulling into storage lot (just lucky). It lost about 20PSI in 25 minutes and was flat the next day. Had I been on the highway I would probably have been able to get to the shoulder before anything bad happened. I use it while on road trips to keep track of the tire PSI and Temp. No guarantees this will prevent disaster in the future but I am happy I have it.
