FOBO Tire is an advanced Tire Pressure Monitoring System (TPMS) using the latest Bluetooth 4.0 that works directly with your Android and iOS device. It also comes with an intelligent In-Car monitoring unit that works on its own or simultaneously with your smart phone. They have recently completed a successful round of funding via Indiegogo, raising 190k out of a target of 25k. The product is now on sale on their website for 175 USD.
I received my FOBO Tire promptly as promised, as one of the Indiegogo funders, and promptly put the device through its paces.
