I like that the numbers are large enough for me to see from across the room. Set up was quick and easy....figuring out where to place the outside unit was the hardest part. The light can be dimmed or turned off which would be convenient for some people....or if you kept this in bedroom. It appears to be accurate. It has a UV index which is important for this area...to remind me to put on sunscreen. It plugs in rather than battery operated---which is a huge plus in my opinion.
