BROKEN merchandise was received. They do not want to recognize the merchandise because IT DOES NOT HAVE a "FRAGILE" LABEL

A good instrument/good price, seems accurate and is easy to use. Some say it looks cheap due to the plastic but the plastic is tough

Great little wet-bulb dry-bulb. It works well and is a great conversation piece. I enlarged the tiny chart provided and keep it near the hygrometer to help explain the readings.

Due to insecure packaging, my anemometer arrived in pieces. The thermometers were loose and the clips were floating around in the box. When I get time, I will use some glue to hold the clips in place so that it will not fall apart again.
