Review on 🔌 Baby Portable Car Fan - Battery Operated Vehicle Cooling Fans with 4 Speeds, Clip-on Electric Automobile Fan for Rear & Back Seat, Rechargeable USB Fan, Low Noise, Easy Installation, 360° Rotation by Byron Patil

It's solid (doesn't sag like some) and I liked the USB function but performance is a little lacking and it broke easily when my son stumbled upon it when getting out of the car seat. The part that just broke was the size of a coin and connected the fan to the base. I don't think a kid should be able to hit it and it's just going to break, especially on a $30 or so product. Otherwise we really liked the fan!
