Okay, so I finally got this little plastic guardian for my thermostat after my nephew kept turning our AC to 'Sahara Desert' mode. First impression? It's like putting your thermostat in a tiny transparent fortress!

The installation was stupid easy – just two screws and boom, done. The clear plastic is thick enough that it doesn't feel cheap, but not so bulky that it looks weird on the wall. And the lock? Genius. Now only I hold the keys to our comfort kingdom (mwahaha).

Pro tip: The air vents actually work! I was worried it might mess with temperature readings, but nope – my thermostat's still accurate as ever. Also love how it makes nosy guests do a double-take when they realize they can't touch my precious climate controls.

Only gripe? The packaging could be better – mine arrived with some minor scuffs (but honestly, who's inspecting their thermostat guard for beauty marks?). For under $20, this thing's saved me from so many 'why is it 85 degrees in here?!' moments. 10/10 would protect again.
