I've had 2, the little donut combo from clam is to brittle, it fell from under 2 ft while setting up my tent and broke so bad it didn't even work. Money spent on something I never got to use.
Second one was given to me, some off brand fan light combo that runs on 4D batteries. The fan works pretty well, doesn't produce a whole lot of light but weights alot and goes though batteries fairly quickly.
I went to Cobb led strips and gave up on a fan in favor of Striker gear that keeps me much warmer.
