Let me start by saying this deflector DOES work – but getting there is a journey. After wrestling with the world's worst instructions (seriously, it's a single confusing diagram), I finally got it installed. The cold air no longer attacks my face at night, which is a win!

The material feels cheaper than dollar store foam boards, and the "adhesive" is basically non-existent. You'll need those included sticky mounts (permanent!) to make it stay. Pro tip: check customer photos online instead of their "instructions."

Adjustability is great though – I angled mine upward so cool air circulates without freezing my workstation. Surprisingly durable despite feeling flimsy; mine survived summer storms.

Would I buy again? Only if desperate. It solves the direct-blast issue effectively, but prepare for assembly frustration and questionable longevity.
