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.

Easy to install
Keep people from changing the thermostat in my home. It was easy to install and comes with two keys

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.

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.

It works good if you want to cover your thermostat
It’s perfect when you’re having rooms for rent and you don’t want people messing with the thermostat

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.

Used for a Sauna Controller so Patrons could see temperature of sauna but could not fiddle. Great that I could mount the cover with out having to first disconnect and remove the controller that I was trying to protect.

De thermostaat werd "misbruikt" door veel te hoge temperaturen te vragen. De beschermkap moet dat voortaan verhinderen. Het is de enige thermostaatbeschermer die groot genoeg is voor de aanwezige thermostaat.
