Query: Outlet Thermostat works great

Have used this in a critical area to keep a warmer set for my birds. Has worked great, has more settings than I use, but followed directions setting it up and it works fine. The error rate is probably about 3 degrees which is acceptable for my use. It is on a covered patio and temps get down to about 30 degrees once in a while and it has continued to work well. The only thing I would like is some kind of indicator that the plug is on or off, like a small light.
