Review on 💨 ObboMed SA-4270T 24V Cooling Ventilated Breathable Air Flow Car Seat Fan Cushion with Adjustable Lumbar Mesh Support for Improved Comfort and Long Drive Solution - Perfect for Trucks, Vans, Boats, and Buses by Scott Ramu

I only used it one day and was very disappointed. I don't know if mine was defective or just bad design. I'm a school bus driver and vinyl seats can be brutal! I was very excited to try this but was unsatisfied with the results! Air did not circulate through the seat as advertised. When I put my hand on the fan, I didn't get the impression that it was "pulling in" much air. There was a feeling that the air was "coming out" of the fan as well (as if it was blocked and had nowhere to go). I figured my sitting on it must have pushed it into the vinyl and cut off airflow, but when I got up and put my hand on the seat I barely felt the air coming out of the holes. Also, I didn't notice any difference between "low" and "high" fan speeds. The only thing I liked about it was the mesh backing (much stronger than the cheap ones you get at most stores). The idea is good, but the implementation sucks.
