Read the reviews and went for it as it seemed to be exactly what I was after. Arrived on time, well packaged etc. The fan itself is surprisingly sturdy but the adapter bit that plugs into the cigarette lighter was cheap and I don't think it would last too long as it's plugged in and pulled out.
I had an issue with the wiring of my fan. The connection between the wire and the adapter broke which meant the fan wouldn't work. Not being one to complain, I tried to fix it myself and soldered it back together. Anyway, a little while later, the fan stopped working - I assume the motor packed in - possibly to do with my repair job, which I accept as my own fault.
When it was working though, it had a fair bit of power and gave a good breeze in my van. Just a shame it didn't last very long
