After a few days using the smart tire safety monitor I would like to make my considerations:
Easy installation, however, using the anti-theft nut I had a bit of trouble to tighten the nut, a wrench with a small angle would be useful for some models of caps that hinder the screw tightening.
Monitoring device monitor:
Interesting design, considering that the device monitor has LED’s to indicate tire anomalies, those users who want to install the device in the dashboard of the car, or even in the console may have problems of simply visualizing which tire has some alert. The slightly larger LED’s allowing viewing over the device would be useful.
Driving at an average speed of 75mph over a distance of 110mi the front right sensor lost communication with the device and after 1 minute the same happened with the front left sensor, I continued driving and after 9 minutes the front right sensor resumed the communication, The front left sensor came back on after 22 minutes, all this happened without me making any adjustments, without stopping the vehicle at any time. This problem has not happened again yet, happened two days ago.
Those are my thoughts, I hope it helps.
