Bought summer 2018 left outside all winter and they still work.
Lost count of how many of these fun and beautiful outdoor lights I have purchased! Loved them so much ♥️ twinkling in the yard at night that I purchased them for friends. They are a nice feature when sitting outside on summer lolnights. Will probably buy more because I do not want to be without them, because I only purchased them last summer and packed them away for winter, and I hope the batteries are still good!
bought 8 of theses lights for our back yard , they change color from red,blue,green,etc. loved them so much went back and bought 10 more. i will be going back to buy more. Love love love them.
