It's a nice unit, but the 200' wireless range must be across open space. On the 2nd day after activation, the system lost the signal from the outdoor sensor, requiring a total reset (15 mins total power-off, which means loss of time and outdoor min/max readings). The sensor was less than 30' from the system box, but there were house walls in between (hard to avoid!).
It's nice that you can stand the indoor box up on a surface or wall mount it, but if you wall mount it, you have to take it back down anytime you need to press either of the two control buttons. You can select which readings are displayed (display mode), but if you select the mode that displays outdoor temp & indoor temp on the top row and outdoor min and time and outdoor max on the bottom row, it will only remain in that mode a short time & then it goes back to the mode where it displays on the 2nd row outdoor min, time, and indoor humidity. And remember, the buttons to change display mode are on the back of the unit. There are no controls on the front.
The solar panels do seem to be quite sensitive, they don't need a very bright light to charge.
The full user manual is only available online for reading or printing (pdf file). The Quick Start guide is provided in the package. The full user manual does not provide that much more info than the Quick Start guide, so it seems like it could have been provided in the package.
All in all, in spite of some shortcomings, the system is well worth the price.
