Yeah, I didn't look to see where the wannabe manufacturer is from, but I suspect this is intended for the casual rider/commuter that hates to put air in their tires. I've known commuters who don't even own a pump, and just put air in at the gas station when they think about it, so....
I can also see this being useful in touring situations, where the tire pressure automatically 'sets' as the temperature changes. Other than that, definitely not for 'serious' riders.
