We live in Minnesota and ordered our lights in Dec 2020 when there was still snow on the ground and frozen ground. We JUST put them up in May only to find out that only 4 of the 9 WORKED. Contacted the company and they said, "Sorry, over 90 day return policy." We just wanted replacements for products that DO NOT WORK. SO - Try them immediately or get stuck with broken products. We will not be ordering from them again
