Product review (5 stars): This is one of my favorite items we use in our rv
This is one of my favorite items we use in our rv. Have the base station sitting on the counter top and the portable pride outside. The batteries last for ever in them both and it is very accurate, confirmed with infrared thermometer. I love knowing outside and inside temp when camping. Also seeing it reminds me to turn the furnace on when needed. I would highly recommend this product.
