Great size. It is plastic obviously so you can break it if you really wanted to but it is pretty strong plastic, doesn't feel cheap. Super easy to install. Easy to lock and unlock to use the thermostat functionality. Comes with 2 little keys. Worth buying. Functions well

These things are functional as far as the cover up the thermostat, but they stick very far away from the wall.

Are you tired of playing thermostat tug-of-war with your spouse or kids? Well, look no further! The TRJ Large Thermostat Lock Box with Key is here to save the day, your marriage, your pocketbook, and potentially your sanityWith electricity at basically the same cost as French truffles in bulk, one really has to think about the thermometer.Child-proofing. The offspring have developed an uncanny ability to turn the house into either a polar ice cap or a tropical rainforest, often just to antagonize each other. But with this beauty, they can pound on that clear cover all they want, but the temperature remains blissfully stable. They ain't got the key. It's like a magical force field for your HVAC system!Now, for spouse-proofing, this lock box has been an absolute game-changer. No more sneaky middle-of-the-night temperature adjustments or sudden heat wave spikes because someone "just needed a little extra warmth." Armed with the key, I feel like the gatekeeper of climate control. It's a small but mighty power trip that I highly recommend and am enjoying enormously.Installation was a breeze. Took me ten minutes with an electric screwdriver.In conclusion, if you're ready to reclaim control of your home's temperature, eliminate the frequency of thermostat disputes, and feel like a superhero, this is well worth the less than $20 dollar price. Five stars! 🌟🌟🌟🌟🌟
