First of all, I want to thank AnyPromo. We ordered from another big site & the fans were all malfunctioning. I contacted Any Promo to see if they could get us an order ASAP as nothing else was available. They worked fast & helped me out a lot.
These worked great! The only setback was the batteries are all shrink-wrapped, rather than having a tab for the batteries. Everyone had to take them out & take the plastic off to use the fans. I assume this prolongs the life better than a plastic tab but also seems like excessive use of single use plastic.
