Good product, easy to use, just plug in and that's it. It seems that it is working as i put this in our mudroom where mostly bugs are and through that blue light, I have noticed it wasn't as much bugs as it is. Very safe too because I am not scared that my toddler will be able to smell something chemical with other pest Repeller. This is very good. I'm glad they have made this product. I'm happy that this product is safe for children, which is my first concern, environmental friendly as well.
