Product review (5 stars): Just as described; arrived in no time; price was good --
So far so good - using this to track the humidity (in three places) in our recently re-conditioned crawl space.  The monitors are easy to mount and the display is super easy to read.  Just hope those batteries last a while as crawling around under our house is not much fun (even now that it's cleaned up).  For the price, this seemed the best option for us.
