Purchased 2 of these at 80 feet long... I wonder if that 80 feet was for each or the total combined. Even if it turned out to be 160 ft., I'm ordering a few more, as the Charlie Brown dogwood in the front yard is def. highlighted as a sad little tree with two janky strings. Bottom line: 80 ft. doesn't go a long way in an 8'-9' ft. tall tree with many branches.Installation is easy, and the light is daintily warm (in a good way) in pitch dark. Wiring is flexible.Suggestion via personal mistake? 1) Measure twice with seamstress tape. 2) Charge for 2 days in direct east sunlight and go out with someone else at night when they're ready to hang so as not to kick yourself come sundown. You're literally "blind" in daylight. 3) Consider buying more than you (think you) may need; you can always find some use for the rest. 4) If hanging outdoors, be sure lights/wires and solar capture thing is above weed-eater level. Yes, it'd be nice to wrap all pretty around the trunk, but finding the splice point(s) and mending it/them with electrical tape -- especially if you've got more than 1 unit -- can be maddening. And you never know how many weed-eating nicks you have in the wire until it's dark. Final suggestion: Zip-tie your solar boxes facing as hard-East as possible for longevity even on rainy days.Overall very happy with the product.
