Product review (3 stars): I really wanted to like this product because it is very accurate
I really wanted to like this product because it is very accurate. I tested the accuracy with a laboratory grade glass thermometer traceable to NIST standards that reads to 1/10th of a degree by placing the display, remote and glass thermometer next to each other and waiting for them to stabilize.  I live in Florida and the ambient temperature was 88.  The remote was faster responding and was spot on.  The indoor display was slower responding (maybe due to the mass of the unit) and sometimes read one degree low.  I had no accurate way to check the humidity sensors but they were within 2 to 3 % of other humidistats I have in the house.  The reason I gave this unit only 3 stars is because of the digital display.  I think the display is very poor because the background is a dim silver gray with black characters.  Very poor contrast.  I have to stand close and be right in front to read it.  This unit replaces a 15 year old Radio Shack digital thermometer that finally died that had a creamy white background and I could read it from across the kitchen.  So, if this unit is going to be on your desk and you turn it to face you, you will be OK.  But if you hang it on a wall make sure it is in a well lighted area and be prepared to walk right up to it.

 I do recommend this thermometer but with reservations.
