Product review (1 stars): Only worked for 30 days.
I bought this one on February 06 and by March 11 the outdoor sensor stop working. The return date ended on March 8 (lucky me). It was nice and basic for the 30 days it worked but wortless after the 30 days. I ordered another sensor on Amazon, and that make this one's price to $35 (in the hope that it's the outdoor sensor and not the indoor unit that is broken).
