This LED mosquito fighting string light is unlike anything ive ever seen before. The strand is longer than i expected which is perfect for, at the very least, cover where we gather in my yard. You may need a couple if you intend to use these to string a gazebo but we just used one side and it was perfect.  The lights are bright but not obnoxious to draw all of the bugs. They give off a nice ambience.  Basically for every other space there is a non refillable container that holds the anti mosquito repellent. I do wish they werent one time use though.  I feel they do laet for an adequate time, roughly a month or so with routine use. A must have in your yard if you love the outdoors but hate being eaten alive! Lol
