Review on 🚗 Enhance Vehicle Safety with CARCHET TPMS Tire Pressure Monitoring System + 4 External Sensors & Cigarette Lighter by Chris Lentz

Updated November 1, 2017: One of the tire sensors was flashing between correct tire pressure and flat tire warning after 16 months of use (less than 10,000 miles because for me it's an old minivan used as a spare car). At first I thought it was the low battery, but the problem persisted even after replacing the new battery. Since the manufacturer's warranty is only one year, the $99 TPMS I bought 16 months ago is rubbish to me. Think twice before ordering this item as the quality is poor. My car is a 2004 Honda Oddsey with no built in TPMS so I went with one for driving safety reasons. I've been using this TPMS system for about two weeks now. Three days after installation I suddenly got an over pressure alarm (41 psi). I just turned off the monitor and kept driving because I haven't pumped up a tire lately and there's no reason one tire would have skyrocketed in pressure while the other is normal. When I got home and measured the one with the high pressure warning, it read 35psi. I also noticed that when I start the car, the tire pressure monitor usually reads 38psi. It drops to the correct pressure, 35-36psi after I've been riding for 1-2 minutes. Therefore, this TPMS does not seem to be very accurate in monitoring tire pressure in a timely manner. It can also give you false alarms when you are driving. I suggest not relying solely on this TPMS to monitor accurate tire pressure or it will drive you crazy if you are a sensitive driver. If you take this TPMS as a benchmark for monitoring tire pressure, especially low pressure, it's fine. If you're looking forward to a TPMS that will keep you up to date with accurate and timely tire pressure information, think twice before you buy one.
