Only draw back I could come up with is my girlfriend is convinced the light is attracting more bugs from the neighborhood. lol.  We have a pool and a pond, along with wetlands on our property, so we simply have a lot of bugs.  This thing is working constantly while it is on.  The zapping can get quite loud, but it is doing its job.  We have it set up about 20 feet from out deck, and 15 from the pool.  You don't want it closer, as it will bring bugs around.  They are attracted to it...which is exactly what you want! Just not right next to you.  Cord it short, so you will need a heavy duty extension cord.  I hung mine on  a trellis, but if you don't have something to hang it from, you may need a sturdy stand...this things is pretty massive, and has some weight to it.
