Review on 🌬️ Adjustable Air Vent Deflectors (4 PK, 4.3 Inch x 10-14 Inch) - Redirect AC Heat Efficiently! by Kelvin Hernandez

The product was a little thin in the middle (it's adjustable but for a 14 inch length, it's not strong in the middle). However, this satisfied my needs - redirects the air from the vent above my desk so it's not blowing directly on my head. Magnets keep it above your head. Easy to install and easy to set up. It only covers half the width of the vent, but is the advertised size of 4 inches (our vents are wider), and I was able to position it to deflect airflow enough. Good price for four of them and they were delivered same day.
