I'm disappointed, the product is not as advertised, I expected something close to what's displayed on the site, what arrived is what amounts to the thinnest gage jewelry wire I've ever seen with tiny light emitting diodes sloppily glued or epoxied onto it. As of yet I haven't seen them work, currently have the light sensor sitting in sunlight waiting, if they work, fine, if not I'll be requesting a full refund. Either way it's a lesson, like the Latin saying says, “ Caveat Emptor” (Let the buyer beware).
