So, it requires way more sunlight than these little lights should and the wires are incredibly thin and fragile. The wires broke several times, just from the weight of the lights, as I was hanging them. I repaired them with wire strippers and electrical tape. :( the company wrote me an apology and said they would send another set. Thought cool, I'd give it a chance, maybe this one was from a bad lot? But, it's been months and it hasn't arrived. Even stronger sad face :(If you are ok with all that, and can repair them too, you will see the patterns are cool. I would suggest going with another option though.We wrapped these lights around two of our trees in our front yard for the holidays, bringing us loads of compliments! The solar panels get a full day's worth of sun (south facing) and one of our friends said they are still lit some mornings when she drives by at 6am - that's a full 12 hours of illumination! I am hoping to use these in the house during other times of the year. I would recommend these to anyone who can place the solar panel to receive full sun. (We have friends who cannot use them because they do not get full sun all day)I purchase these lights for my mom. She placed them on her hedges and she love them. The lights were visible and shone brightly during the entire night.Very awesome!! We live on 3/4 of an acre and have "Christmas Trees" lining the back of our property. We bought these solar lights to light up our trees during the holidays. The lights have survived several storms and several feet of snow in Iowa. Our neighbors were very impressed with the light glow of the trees in our yard! The different lighting function was fun to play with, too.UPDATE!!! 12/31/16 as with other customers - after a few weeks my lights just stopped working! Boo!While I didn't like waiting an extra two days to get this, I didn't take that into consideration in my review. What a liked - that the lights were indeed, already charged! The settings work very nicely! What I really dislike - warm white = yellow. If you want white lights DO NOT THINK THAT WARM WHITE IS WHITE! Very disappointed in the color!We are very disappointed in these lights. They are very dim compared the the last set of solar powered lights we owned. Also they randomly change settings and start flashing. I would not purchase them again.So far these are awesome. They're less bright than traditional lights, but makes them look that much more like glitter or fairy lighting. They're bright enough for decorations for sure though. Also love how light (weight wise) they are. Makes it easier to decorate weaker limbed bushes that I have.NOT VERY BRIGHT
