Everything, in general, is of very high quality. Once the tires have been fitted, the tire pressure sensor will alert the driver even if there is a differential of 0.05 to 0.1 bar. Only the fact that the pressure is different is brought to my attention, not the pressure itself. This pump will no longer cause any issues. Prior to that, there was a pump that utilized a traditional pressure gauge, and there was also such a challenge. It does so quite quickly. To be able to go around the entire car on one side, I would need to extend the cable, which is something I plan to do after the warranty expires. Even if you hook it into an outlet in the trunk, there won't be enough power to charge all of the wheels. On August 23rd, 2022, I made a purchase for $3,160. If it stops working soon after purchase, I will revise my rating. On YouTube, you may find millions of different reviews about it.
