we used these as door prizes for the golf tournament and they went over very well.
great price for the bulk that I got
Nice sturdy cup. These were way more popular than I expected a plastic cup to be.
We had quite a few that didn't work when they arrived because they were missing the little plastic disc that prevents the batteries from running out. It would be better if they used a more conveniently/common sized battery. The ones that weren't dead were great though, super bright.
These are a big hit with our boat captains. Good way to advertise too.
