Let me start by saying this deflector DOES work... once you survive the assembly process. The first night I installed it, I finally slept without that icy AC wind tunnel effect – total game-changer for my night sweats!

The good: It successfully redirects airflow in multiple directions (up, down, diagonal). I only needed 4 of the 6 adjustable panels to stop my AC from assaulting me during Zoom calls. The lightweight material does feel cheap, but hey – it hasn't cracked after 3 weeks of use.

The bad: Those 'instructions' are practically hieroglyphics. Mine arrived looking like a plastic burrito – all rolled up with 30+ confusing pieces. Pro tip: Check customer photos before attempting assembly. Also, the 'stick-on' claim is misleading; those mounting brackets are permanent adhesive, so position carefully!

Real-talk moment: This feels like a $2 product marked up to $15. The foam edges resemble craft store leftovers, and during assembly, I definitely muttered 'this better work' at least twice. But here's the thing – despite its flimsiness, it solved my specific problem of freezing AC drafts.

Best for: Renters who can't modify their space (like me!) or anyone needing a temporary solution. If you want premium build quality, keep shopping. But if you're willing to wrestle with assembly for functional airflow control? This oddly gets the job done.
