Batteries are crap. After 2 days in full sun, they only lasted ~1 hour – had to replace them with some old rechargeable batteries (much brighter now and last all night). One arrived with a broken clip as well. Better than the other Touch Of Eco string lights I got from Woot… at least these ones didn’t have the solar panel drop off when they were taken out of the box. Never buying Touch of Eco products again!
