Needs a full charge to spin
You put it in the sun, It charges up.  There's an on & off button.  Turn it on and it spins very slowly.  You can't keep it on all the time.  I don't know why it doesn't recharge itself while it's spinning and "on".  But it will stop spinning when the charge is done.  You have to turn it off to recharge.  Kind of a pain since mine is hanging from my balcony.  No instructions came with it.
