Product review (5 stars): So glad the old on gave up the ghost
I bought this unit to replace an old one that just stopped working. So glad the old on gave up the ghost. This one is far superior! It is about half again as big and I can read it half way across the room. I didn't need the clock on the old one and never used it. This unit has humidty for both inside and out which I did want. All in all I am very happy with this purchase.

It is recommended that you use lithium batteries which I didn't realize. Not a problem as lithium batteries tolerate heat and cold better. Or so I'm told.
