Work very well
They are well calibrated (accurate). Suggest using and comparing to the mechanical versions - the error is amazing to watch (wet/dry bulb very accurate$

Kind of cheap, but it does work
One just has to be careful w/this device. The bottle is so small, the water there evaporates in a few days.

A good instrument/good price
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

Device arrived in pieces
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.

Absolute $#@% quality; do NOT purchase
This was simply one of the all time worst quality pieces of crap I have ever had the misfortune to purchase. The cheesy plastic bottle's top was broken and the thermometers read differently in the dry state, without attempting to add water to the one with the wick. Do NOT waste your money on this garbage.

Great little device
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.
