Product review (5 stars): Love this set
This thing is awesome so far. I have tropical animals in a separate building and a greenhouse. I need to keep an eye on the temps in both of those. The alarm feature is really cool. I have it set to tell me if the iguana house falls below a certain temp at night. So far I haven't heard it go off so I can't say how loud it is but I don't want to find out either because then my animals would be cold lol. The outdoor sensor is in my greenhouse and often gets wet. So far so good. I should have bought this a long time ago. I kind of want more sensors so I can track the temps in all kinds of places around the property!

I do have one indoor sensor upstairs that has stopped communicating. Trying to figure out why before I contact the company.
