Product review (1 stars): I'm thinking cool, a new unit
When I received my meter I tried to calibrate it. After calibration it would not show wind speed at all. I contacted Amazon and they contacted Ambient Weather. Here's where it gets weird. Ambient would not let me return it to Amazon and wanted me to provide all receipt details before they would authorize an RMA. So, I did all that and Ambient sent a return box with a new unit. So, I'm thinking cool, a new unit, tried it right out of the box and wind, speed, temp. and humidity all work but need to be calibrated. I followed the directions and it did the same thing the previous one did, no wind speed. So, I gave up and moved on to humidity,followed the directions, and boom, no humidity. Next, I called the tech. rep. I explained to him what happened so he grabbed a new unit followed the calibration instructions and boom, no wind speed! He then tried humidity and that also failed. He told me there was definitely an engineering problem and to please put BOTH units in the box and send them back, which is what I did. Wow, this only happened to me????
