Product review (1 stars): HUGE DISAPPOINTMENT !
This product is good in concept, but Lacrosse's execution sucks.  The units are very finicky and work when they want to... or not. Their website says support turn-around time is 3-5 days.  Well, that's unacceptable if you're remotely monitoring temp and humidity/water.  By the time Lacrosse gets back to you, your house is frozen or flooded!!  But the worst is that they don't even live up to the 3-5 day standard: there is NO SUPPORT.
(1) Their phone lines are not manned, so the system asks you to leave a message.  Messages are not answered; no return calls !!!  (2) And don't bother to email them using their online "form submission" page.  They do not reply to them either.
(3) They don't have manuals for their products... just a short set-up sheet which is lousy.

So do not buy this product.
