Let's talk about this adjustable AC air deflector. First off, the concept is brilliant – redirecting that harsh AC blast away from your face while improving air circulation? Yes, please!

The installation was surprisingly easy. Just slot it into the AC vents, no tools needed. I loved how it telescoped to fit different unit sizes (56cm-106cm range). The multi-hole design does help distribute air more evenly, reducing those annoying cold spots.

When it worked, it worked well. In my bedroom, it stopped the direct icy blasts that used to wake me up shivering. The hollow waterproof design means no worrying about condensation drips either.

BUT... the durability is questionable. Like other reviewers, mine started failing after just a few days. The adhesive gave out first, then the plastic clips snapped when adjusting angles. I had to MacGyver it with tape, which sort of worked but looked terrible.

The energy-saving claims seem legit – I did notice the room temperature became more consistent rather than having that AC-on/AC-off rollercoaster effect.

Final verdict? Great idea with mediocre execution. If they improve the build quality, this would be a 5-star product. As is, it's an okay temporary solution if you don't mind some DIY fixes.
