Query: So convenient!

I got this as a gift for someone who complained of bugs that filter in every time her door to the yard is opened. Her ceilings were fairly high, making it difficult to cath the ones stuck to the ceiling. I searched the web for this tool because this is sold everywhere and readily available in Korea, and I was happy to find it on Amazon.com! The person who received this as a gift absolutely loves it!
