Works great to keep family from fighting over thermostat
It looks big on the wall but it fits the thermostat perfectly. Just what we needed to keep people from fighting over control of the thermostat. Definitely worth it if family can't agree on temperature for the house.

Take note of the inner dimensions
Nice, high quality case, but take note of the inner dimensions, specified in the description.

Super Big!
This was prefect and easy to install! We have a really large (Emmerson) thermostat, and I had bought a couple other "universal large" covers but they where too small. My Mother has Alzheimer's and turns up the heat at 3 am(we live in the desert) to 95'. So this is a great safety measure.

Perfect
Nice and big and it should get the job done! I'm so sick of coming home to find the A/C turned off because the 70 year old man is cold in 80 degrees.

Very cheap made
Was very easy to install. It would also be very easy to get into without the key. Yet using the key is a nightmare. The key fit is terrible. Would not purchase again.
