Review on Wintact Handheld Anemometer Small Digital Vane Wind Speed Meter Gauge, Pocket Air Flow Velocity Tester With Measuring Wind Temperature 14℉ To 113℉ For House HVAC Duct Outdoor Kite Boat Sailing Surfing by Matt Dyen

I bought this after returning a similar product that actually cost a few dollars more, and yet which had proved wildly inaccurate. This unit is very, very compact. It comes with readable directions and it is fairly accurate. This is the one to get if one is interested in something handy and small, and does not want to upgrade to larger units that will require larger batteries, e.g., 9 volt or two AA.
