I bought 2 small ones and one large one in the blue color. They are beautiful and are really spectacular lit up, with the rest of the room dark. For the Christmas holidays and other occasions, I use them in front of a large window, hung at different heights, or sit them on a table near the window. I would love to buy more but the lights do not burn anywhere near the time it says they will. The lights seem to go out in clusters, with half of them out on one sphere, and at least a third out on the other two. They are not scattered outages, but are in one area, and the lights on each sphere went out all at once- not just one or two at a time. You can't replace the bulbs apparently.
I've thought of spray painting them some glowing color but I think that would make them look cheap. If the lights stayed lit even near the amount of time it says they will, then this would definitely be a 5 star item. But I can give it no more than 3 stars. Even though I bought all of them on sale, they are still too expensive for the amount of time you can use them. Perhaps if the price is reduced low enough, it would be worth it to buy these for one holiday season and not expect any longer use from them. Then just hope they'll last through that one holiday week.
