Product review (2 stars): Surprisingly small amount of useful data given the size of the screen
The LED backlighting is nice but with all the screen space there's no way to display multiple temperature sensors without cycling through them. A full 1/4 of the screen space is taken by the useless (to me) inside temperature measured at the unit head. I should have read the manual before ordering, I would have discovered that the top line is not changeable (its pinned to inside temp) like on other ambient receiver heads. Given the amount of heat the backlight generates I'm not sure the inside temp is of much use, it does consistently read higher than another ambient receiver head sitting next to it.

The bar graph is pretty useless in practice, it auto scales so its hard to tell if the temperature just went up a little or a lot w/o looking at the tiny text on the Y axis. The phase of the moon is nice. Programming and adjusting the display is not much fun and pretty counter intuitive given almost no useful feedback on the display and the small number of buttons. Do not lose the manual as I find myself cracking it open to get the right 'chord' and timing to play on the buttons just about anytime I touch the thing.

I realize this might be more useful to someone who just wants 1 outdoor sensor and cares about the indoor temp at the receiver.
