Actually has some pretty nice features for the money but the overall size of the receiver is a lot SMALLER than the promotional photos suggest. In fact, the "display window" itself is only about 1/2 inch high and maybe two inches wide. Given the amount of graphical data to be displayed, that's LITTLE! Also, it took a lot longer to program. than I expected, especially since the little instruction manual is written so small that you need a magnifying glass to read it. Believe me, I'm not kidding! On the other hand, it has a nice loud alarm sound. You know the problem , and the six small TPMS caps have enough signal range to work well on my 25ft Class C RV. Also like the receiver's ability to charge both via the small solar panel on top of the receiver and via the included USB Cable . Overall it seems to be working and I'll feel a little safer on the road with the device installed.
