Product review (5 stars): Good for the price
Product packaging says it's just a thermostat when it arrives, but it actually dose perform and look like the unit in the pictures. Seem to be holding within one or two percent of my humidor- I use a xicar charged with 70%rh solution. I don't believe it's meant for a large environment as it fluctuates a bit in a room our outdoors, but seems to get the job done for the price.
