My friend had a bug zapper and I thought this item would be comparable. Wrong! His item was purchased at a Harbor Freight store. It sells for $2.99 there. This item from Amazon is much inferior to the one from Harbor Freight Unfortunately, I didn't learn about the low cost of Harbor Freight until after I had bought this one. I was hoping that it was a better product, but that is not the case. Harbor Freight's Uses "D" batteries and the racket part is made of a mesh so that some small insects can't fly through it. The one from Amazon uses "AA" batteries so won't last as long on batteries. I made the mistake of buying the one on Amazon, so I will just mark it up as experience. Will make me check further on merchandise when I buy from Amazon.
