Bests & Worsts Reviews from Amazon

I ordered four Strings to hang across my backyard and they looked great for about a month- then one night they were on during a light rain and my wife noticed they went out. I investigated and found that they had blown the fuse of the outlet they were plugged into. I got the switch reset but the lights did not come back on... I tried each string individually and even ordered replacement bulbs to see if switching them all out would help, bit I now have four dead strings. I'm baffled as to what has happened exactly, but for lights intended t be hung outside they sure don't hold up to the elements very well...
