Work as advertised. Working fine outdoors so far. Prompt shippingThe string lights are colorful and pretty, they also come with batteries, it’s value for money.These faux cork lights are very tiny and fit easily into most bottles. I enjoyed trying them in bottles of different shapes, sizes, and colors. The lights last a long time but sometimes seem to dim for a bit before glowing more brightly. They look nice displayed in a group.These are great for lighting up wine bottles as accent pieces. The "cork" will fit most wine bottles, but if not, just lay the bottle on its side for a different look. The lights are bright and I appreciate that they are all individually packaged with the battery pull tab so there isn't excess battery drain. The batteries themselves are easy to replace and easily accessible. Highly recommend.I included one of these string lights along with each bottle of wine I gifted to friends, so they would have something to display even when the wine was gone! Love the unobtrusive approach to integrating the battery pack.These are so simple to use, very beautiful. The fit a basic sized cork bottle top.These cork lights are beautiful and easy to use. A very simple way to decorate with bottles and add some ambience. I especially love the way these look in bottles made from tinted glass. The top fits on the top of most bottles, just like a cork. I only have 1 booze bottle that these don’t fit in because the opening is too big (Crystal Head Vodka) but I was able to fix that easily by simply wrapping a hair tie a few times around the cork and setting it in the bottle opening and that keeps it from slipping.Probably my favorite thing about these lights is that the battery compartments are held shut with screws which makes it so much easier to swap out the batteries. Each little cork takes 3 LR44 batteries (which are included) which are small and very dangerous if swallowed by pets or children so make sure these are kept out of their reach.I only tested them to be sure they all came on, and they did. I don't see or anticipate any issues with them. I plan to keep them for a future bar setup.
