Cute bright and colorful but very delicate, did not work in Bobo balloons. Broke easily or were defective after simply unraveling. Might be nice for a mantelpiece or centerpiece that won’t be used much. Left me frustrated and cost a ton of money to replace all my lights with better made fairy lights.Defective, come on then will not stay on. Open battery pack, close, work briefly, off again. Tried 12, all the same issue. Refunded by Amazon. I have been using this type of light extensively for years. First issue. Bad battery packs.I did not rate as highly in battery life because several of the lights were blinking when I turned them on. Yes, I actually tried out each of the 100 lights so I could sort out the different colors of lights that I had available. These were much longer than I normally purchase. These are 10' but I prefer 6'. However, this set of lights was a phenomenal price. I can always purchase more batteries as backups to the items I am making. Great job on this set!In my set: 12 red, 12 pink, 12 lt. purple, 12 blue, 12 bright white, 16 soft white, 12 green, and 12 multi-colored pastels.
