Have had mine running for 10 months nonstop now, cleared out all the blind misquotes really fast. It does have to be cleaned initially when there are a lot of bugs, but I simply blow on it and then use a thin wooden stick to knock off any large dead insects. What a relief to be able to walk out the back and not have a cloud of bugs get in my face and coffee! Had the UV bulb starter blow after 10 months and they sent me a replacement UV bulb starter right away "for free" with proof of purchase (it only cost $2.38 if I ever need to replace it out of warranty). The replacement part was modified slightly, I am guessing to make it last longer (had better wiring connection). Made in the USA, have to love that, and very well made. Has taken the Florida heat and rain just fine. I just bought a second one for the front of the house.
