Let me start by saying these retractable AC deflectors are GENIUS in concept. The adjustable length (570-1030mm) means they fit most wall-mounted units, and the 180° rotation lets you redirect airflow perfectly. I installed them in our bedroom to stop the Arctic blast from hitting my side of the bed directly.

The PP plastic feels surprisingly sturdy when extended, and the white color blends nicely with our unit. Installation was a breeze - just peel and stick... at first. Like another reviewer mentioned, one side started peeling after about 3 weeks of use. I tried cleaning the surface and reapplying, but it just wouldn't stay put during nighttime cooling cycles.

When both sides were secure though? MAGIC. No more waking up with that weird 'AC face' from cold air blowing directly on you all night. The telescoping design makes it easy to customize the airflow direction - we could even create a gentle upward curve to circulate air without the direct blast.

For the price (especially getting two in a pack), they're worth trying if your AC is making someone miserable. Just be prepared that you might need to reinforce the adhesive or find alternative mounting solutions long-term. Maybe some heavy-duty double-sided tape would solve the peeling issue?

Final verdict: Great when they work, frustrating when they don't. If PATIKIL improves the adhesive quality in future versions, these would be absolute must-haves for any bedroom with aggressive AC airflow.
