Product review (4 stars): This Is A Gift So I Didn't Test It - Looks Beautiful & Is Much Larger Than Picture Shows - Very Large Easy Read Digits
4 STARS -  Only because It Is A Gift And I haven't tested it yet. That said - I own the smaller $10.00 Version for my room Temp/Humidity only and it functions Flawlessly with Supreme Accuracy.  So I'm Expecting The Same Quality, Performance, and Accuracy from this Outdoor/Indoor Wireless Temp/Humidity Gauge also.

OVERALL MEASUREMENTS:
Large Stand Up Display -
5.25" H x 4" W x 2" Deep
Outdoor Temp/Humidity Digital Number Size::
 1"H x 1"W
Indoor Digital Number Size:  3/4" H x 3/4" W

Wireless Sensor Measurements:
5.25" H x 1.5" W x 1" Deep

BOTTOM LINE -  This Product Is Plenty Large, Extremely Attractive, Easy Read and Quality Looks Good. Does not come with batteries - so make sure you have have 4 AA batteries on hand while waiting for delivery.

Until Tested I'm Very Pleased & Impressed With This Purchase at this point in time.
