Because the main unit uses 3 batteries. And all the remotes are battery powered also.
Where the competition uses 2 batteries each.
Personally i'd get a unit where the Sensors all have Tempeture and Humidity LCD's on them also.
Update. Looking at reviews it shows some reporting temperatures of 19F.

I don't know what's in the liquid but based on experience, it freezes around 32°F and the display will stop working. It'll resume working when the liquid thaws. What concerns me, however, is the possible damage to cheap displays with repeated freezing and thawing. Water expands when frozen, which may stress the LCD's components.
