Ordered a two pack. The one likes to decide wether or not it’s going to light up. They both get the same amount of light. I think the one has a bad wire. I can’t select the mode on that. And it just blinks and twinkles. Flashes and is a nuisance. So out of the 2 pack I got one good one.These lights are very durable. I put them up 11 months ago and they are still wrapped around my oak trees and still come on every night and shine just as bright as they did when I took them out of the box. They have endured brutal winters of -15 temps with ice and snow and have also withstood 98 degree humid heat. Recommend these lights!We put two strands on a six-eight foot evergreen tree located outside, near the road, away from any power source. They covered the tree well and after a sunny day were visible from a couple hundred yards/meters away for several hours (up to 6). On cloudy days, sometimes they might not last more than a couple hours and be fairly dim.One issue is that even with the solar collectors right next to each other, the strands would run out of power at different times so that the tree would be only half-lit for the final hour or so. But by then it was late and who cares.Summary - hey - they're cheap and for that price, they did great. Got lots of compliments from passersby. Do I wish that they would last longer? - YesI've had these lights up for a few months now they last all night until morning they're very nice and I plan on buying more definitely worth the moneyI installed these lights on two trees outside in minutes. Really easy to use, but I wish they were brighter. Pretty though.Loved the ligjtsI brought these lights for Christmas 2021, and they are brighter than fairy lights but dimmer than the usual led Christmas lights. where I live it doesn't snow and we still get sunshine till 5pm in the winter time. So we had no problem with them turning on at night, the lights stayed lit up till the morning. If these lights had the same brightness of the usual led lights you see on exterior Christmas lights, it would be a five out of five stars.Replacing a similar product. I use this to illuminate a glass gazing ball on a pedestal.I like the multiple lighting pattern options. A few can be rather intense I prefer the twinkling one.Charges reliably and lasts through most of the night
