As another customer said they were not made correctly and the AA battery is not strong enough for the fan to work properly. I bought 4 of them (all are coming back) - one worked (albeit slowly and intermittently) the other three just needed shaking to get the battery to touch the connector and it worked. Why are they even on sale? They had to be taken off the shelf and sent back to the manufacturer.
