I got a big leak warning before my car's low TPMS pressure kicked in so this is definitely a must have for anyone wanting aftermarket service. It's also cheaper to repair than an OEM since you can just buy another kit, which is another plus for it. Complaints only about the sensors and receiver, which would be nice -> Sensors are smaller as they look like giants and are easy to spot. -> As for the receiver, it only fits my awkwardly angled lighter as the lighter is deep and narrow, so I'm lucky the receiver even fits in there. Maybe only my machine has this problem. Anyhow for the price it's an amazing product that pays for itself when it alerts you to a pressure problem, low pressure is the number one cause of flat tires which I've learned the hard way. The product seems to work great on my sports car. Also note that this is not "plug and play" as unlike a handheld pressure gauge, when you plug it in and it automatically gives us a reading it looks like all aftermarket TPMS systems require the vehicle to be driven at high speeds at least 20 mph or something for you to be able to read. So don't think it doesn't work until you start driving
