Review on 🚗 Smart Car Tire Pressure Monitoring System - 6 Alarm Modes for Universal Vehicles - Wireless Solar & USB Charge - 4 External Cap Sensors Included - Real-Time Pressure & Temperature Alerts by Craig Mcdonald

I wasn't expecting a great unit at this price but if you browse the market you will find the same model under different names and this model was the best for the price. from all. I had to replace it with a similar one that was frozen on some of my numbers, from a different seller and with a different name but identical. I tried this option because it's easier to pay less than thirty dollars and get it the same day than it is to deal back and forth with a company (which I had to deal with). poor communication in english, late reply, ridiculous decisions. The fact is that my predecessor could be defective. To the device itself; it displays pressure and temperature as described but is very sensitive and does not display the same pressure on all four wheels. Let me explain; I'm a complete nerd when it comes to tire pressure. I have my own nitrogen cylinders and standard electronic pressure gauges. The pressure I use to put the caps on my wheels is on the limit of 0.5 and the full number (30.5 -31) I need 30, but removing the pressure gauge and putting the cap on (on all wheels carried out in the same way) gives 0.5 psi. Annoying thing about this unit is a discrepancy between the wheels in one psi randomly, and randomly I'd like to say that's not a lower pressure on one side of the car. I always press after the car has spent the night in my garage so there is no problem with my gear. To use such a device also under the conditions described. The device displays the actual pressure in your tires at all times; Pressure is temperature dependent, so you will have different readings while driving. The key is to know your device and understand variations and watch for anomalies. The device also warns you of over- or underpressure. It's perfect? Absolutely not. Can it be used? Absolutely! Does it bring confidence to the road? Absolutely!
