Product review (3 stars): Does what it needs to, but a few features are unclear
3 stars: Because, for the price, I thought it would have more flexibility in the programming

This thing does what it advertises.  I have 4 sensors on it.  3 temp/humidity and 1 freezer/fridge.  Range seems OK after initial setup.

Some things I wish I'd known before buying:

-Alarms can only be set on channel 1, which is the default outdoor channel, not on multiple sensors.  So if you want an alarm on your deep freeze you have to accept some of the charting things are going to be less useful and you can't have any other alarms.

-The backlight with its mood ring color changes can be shut off by holding down the top button for a few seconds.
