Review on 🚗 TYReXCEL TPMS 4 Sensor Economic Type: Real-time Temperature & Pressure Display for Car RV SUV MPV Sedan by Tyrell Christmas

My car already tells me when one of my tires is low, but it doesn't tell me the temperature or PSI. Temp may not be useful for my purposes, but knowing PSI is really helpful. Installation was easy, but still took a little longer than screwing on regular caps. Special caps included in this kit. Each cap is marked FR, FL, RR, RL and belongs to the corresponding tire. After each cap was installed, I had to tighten each lock nut to prevent theft. They keep the cap in place well, but it adds an extra step and time when I need to fill up my tires with air. I have my own compressor so I can do it at home, but that makes things more difficult. The kit comes with a wrench to tighten the locknuts, but it's very cheap and flimsy. I might have to find one small and thin enough to get the job done and leave it in the glove box just in case. Surely the one they turned on won't last long. It took several minutes for each cover to be recognized by the display in the parked car. They work faster when I'm driving over 25 mph. The tire caps are a bit heavy and I wonder if they unbalanced my tires. I have included in this review a picture of one of these tires alongside a regular tire and quarter just for scale. They're pretty big. The display unit has to be turned on manually and I'm not sure if I remember this or do it every time I get in the car. It is solar powered and has a mini USB power supply option. I would have liked more if the USB option would automatically turn on the display when the car is started. Each tire cover is powered by a battery. Let's see how long they last before they need to be replaced. The gauge is only 2 digits and is not as accurate as my compressor which reads tenths of a PSI. So 40.1 on my compressor reads like 39 on this display. I think it's useful, but there's room for improvement.
