Very functional and of great quality in all materials. To read the manual, I used Google Lens. You have to carefully install the sensors on the wheels, first the nut and then the sensor. Setting it up takes a bit of effort until you learn the sequence of tightening on the indicator, but with patience it works great and if no monster destroys it, it will be very useful. However, if you buy the one that fits inside the tire, it will be safer here in Brazil. Thank you, friends from China.

The quality seems good for the price. Installation is easy, and communication starts immediately after installation, so the tire pressure is displayed right away. It displays not only pressure but also temperature, making it more reliable. However, since it's a protruding external design, it doesn't look very pretty. There seems to be a bit of a risk of it getting lost. But I am very satisfied with this level of performance for this price. It seems that solar charging works well.

The package arrived quickly - in two weeks to Kherson. The product matches the description. Everything works correctly, displays everything accurately, and installs quickly. I recommend that after installing all the sensors, with the device turned on, simply unscrew and screw each sensor back in. Please note that if the actual pressure is, for example, 2.21 bar, the device will display 2.2 bar, and if it is, for example, 2.18 bar, the device will display 2.1 bar. That is, if I were to round it up. Upon arrival, the circuit board was a bit loose inside - simply placing a piece of foam between the board and the cover made everything quiet. After a while, the device at the parking lot turns off; as soon as there is some movement, it turns on again. You can manually turn it off if it becomes a nuisance. I recommend it for its price and quality.

Good seller, fast delivery, received in Ukraine in 7 days. Thank you! The sensors are quite accurate, the system was calibrated at the factory in Barah and set to degrees Celsius; you just need to turn on the unit and calibrate the sensors. If a sensor did not synchronize the first time, you need to unscrew it and, after a short interval, screw it back on. It automatically switches to sleep mode and turns on with the slightest vibration.

Works well, easy to install. No complications during installation, it's almost intuitive. The interface is readable and easy to use. You can set an alarm for limit pressures, too low and too high.
