These lights are really cool! I have put them around a &#34;fairy ring&#34; in my yard. The only thing that I wasn't super happy about is that they are not really white. I guess you can tell that from the picture but I didn't realize it until they were out there next to some of my other solar lighting that is pure white. Everything else about them is perfect and I can live with the color difference.
These lights are okay. Just very very tiny. The size of a dime. I ordered fairy lights and got these chuzzle ball lights.
These are SOOOO CUTE!! They could be a little brighter. They are definitely for decoration and not for illuminating a space.
There are lots of lights and if the LED solar keeps working, I am going to be tickled pin. Very nice set
Love them! a warm white light, we have 3 sets in our garden trellises got the cool flower fairy to complement, looks &#34;starry&#34;, we love the effect,
I received it super fast which was great, but it's way smaller then I expected. And yup, just like the reviews said, it has a short. I purchased 2 of these too. Talk about a waste of money.
I have these on my chandelier in my gazebo. They go on automatically at dusk and make it look beautiful.
I had a lone little tree I wanted to put something unique on for Christmas so I ordered these and a set of warm white ones. They are really cute! But the shorter days only charged them enough to be bright if it was perfectly clear and sunny all day - on cloudy days they were a bit dim. We never had snow while I had them up (ironically, it's been super snowy since) but I'm sure any snow would make them unusable as well.
Answer: no
