Well, I do carry a tire pressure needle gauge. It's more accurate than the other style of gauge.

The biggest reason for getting the Orange device is to get information that's readily available from the vehicle. As I said, I'd like to get the information from OBD2 but it's not readily available. Likewise, it's not on the infotainment display. This device will allow me to get this information easily and hopefully at a reasonably low cost - under $150 CAD.
There are various bluetooth devices that measure air pressure at the valve stem. They will come out at almost the same cost as the Orange device. I've had issues with valve stem indicators causing slow leaks as they cracked along the seams that held the cap together. I'm also not convinced they are as accurate as a device inside the tire itself.
Tire pressure is something we should all check regularly but don't. When we do, its often at the gas station beside the air pump. At that point the tires are warm and will not give an accurate reading. Tires need to be checked cold which is something very few prepare to do, Few people make time to do this properly or have portable air pumps to pump up their tires. Yes, I do have one from Canadian Tire and have used it many times.
The other sad reality is that too many people "check" their tire pressure by visual inspection. Tires simply don't give visual clues that will indicate their actual tire pressure. This is the point of the TPMS - to give a warning that
the tires need attention.
So hopefully between the Canadian distributor of Orange products and Orange Electronics itself, I get an email back letting me know if I can get this product to try it out. I think it will be quite useful and will be of interest to many persons.
