This device was exactly what I needed. It definitely works to spec and tells me the tire pressure of my Honda Goldwing F6b every second. It was very easy to install, it worked right away and the display is very clear. My only issue is that the manual was difficult to read - it's too small, but that's not a problem with the functionality of the printing system. I definitely recommend this product. UPDATE 6/14/17 I'm updating this review because my system has finally stopped working. I bought it around June 2014 so I've had it for about three years. I'm not sure if that's a normal lifespan for a product like this as it cost me almost 200.00 but thought it would be important for you all to know how long it took me. My only improvement would be that there is a way to keep the display light on at night for night driving. Otherwise, if you drive with gloves at night, it will be difficult to press the display backlight under the light while driving. I will be buying another tire monitoring system, not this one but a cheaper one at around 100.00 as I believe at this price point this system should last more than 3 years.
