Big scam, stay away, it didn't work properly for even 2 weeks, you can't seriously rely on this, you definitely need the original warning light from the car. It doesn't always reset when the car is off, I connected it with a T-joint on the trunk, as soon as the car warms up a bit, the needle goes up and down above and below 0.5 bar and it keeps getting worse... Also, the low-pressure alarm doesn't work, probably because it's a fake. That's it, if someone wants to risk it, connect it with a hose away from the trunk and the heat because it is very affected by them.
