Let me start by saying, if you're tired of freezing under the direct blast of your AC, this deflector is a game-changer - especially for the price. I've been using it for about a month now in my bedroom where the AC vent points directly at my bed.

The installation was surprisingly easy despite the Chinese instructions (thank you Google Translate!). The card slot design slides right into your AC vents without any tools. What I love most is how you can adjust both the length (from 56cm to 106cm) and angle to perfectly redirect that icy wind away from your face while still keeping the room cool.

Now, let's talk about build quality. Is it premium? No. The plastic feels basic but definitely sturdier than those flimsy acetate sheets I've tried before. For something at this price point, it's more than adequate. The hollow waterproof design means no worrying about condensation buildup either.

One thing to note - if you have a powerful 2-ton unit like one reviewer mentioned, this might not open wide enough to handle that much airflow without affecting cooling efficiency. It works perfectly with my standard bedroom unit though.

My favorite feature? Being able to finally sleep without waking up with that weird stiff neck from cold air blowing directly on me all night. My toddler's room stays comfortable without the harsh direct draft too.

Is it perfect? No - but for under $20, it solves a very specific problem remarkably well. Just don't expect luxury materials at this price.
