I Use these at two different parties. First party was highly effective it lasted 14 hours and the card was never found.The second card was also effective only took three hours to fine but drove the dogs nuts plus the glitter was a icing on the cake!
Hotel rooms are an amazing spot to put these!!
I had our supervisors looking for hours one office got the cricket and the other had the bugle horn. So very funny and the whole plant knew what was going on.
Loved the product, but the batteries last more like 4 hours than 8.
Great fun! Meows for 14+ hours.
