I was worried because it was made in China, but after charging the main unit and installing it in the correct position, the numerical value was immediately measured and the accuracy was 100% when compared with the scale using the compressor. Highly recommended! :)

When you put the air pressure, never put it in the TPMS standard, and the numerical value is only for reference. Only the FL side has a low air pressure, so I inquired, and they said that an error of 3 to 4 psi is normal. However, not all of them have an error of 3 to 4 psi, but if only one side has an error like that, an accident will occur if the air pressure is adjusted based on the TPMS. The numbers are just for reference. I was expecting too much, so I'm very disappointed.

Delivery was ordered on 2.1 and received on the 2.21st. Please note that the product is satisfactory. It's easy to install too. When installing, there is a bolt that is inserted inside to prevent theft, but I thought it would be cumbersome when inflating the tire later, so I just installed it without it. I can't help it if I steal it
