I really liked this fan at first. I bought it for my daughter's car seat. It's small, handy and performs well, but now that I've had this fan for over 2 months I'm looking for another one. The hinges on the fan are now too loose to stay in place so I can't install it anywhere without the fan twisting away. I bought a mini screwdriver to carry around in my diaper bag. If the fan comes loose I can just tighten the screws and the problem is solved, but unfortunately the bottom screw is not accessible unless I take the entire fan apart (which I've had several times) just to pull it up. If you install it without moving it all the time, you probably won't have a problem with it. However, if you move it from the car seat to the stroller and everywhere, constantly adjusting the angle, it won't last long.
