Review on Stay in Control of Indoor Climate: Ambient Weather WS-03-3 Compact Temperature and Humidity Monitor, 3 Pack by Charles Fowler

These humidity and temperature gauges appear to work well. I bought a set of three so I could have a chance to install them all in the same place to see how consistent they are. They all gave the same humidity and temperature readings. Okay, sometimes one reads one grade higher or lower than the other, but they're close enough for my needs. Only time will tell how long the batteries will last. I bought them for my apartment in Florida. I can install one in the living room, one in the bedroom and one in the guest room. This is a nice compact size that can be hung on the wall as well as mounted on a dresser. I think they are good value.
