We liked the length of these and the fact that they plug in instead of needing batteries. Unfortunately, we were gently untangling them and one of the wires snapped, causing a large number of the lights to go off. I managed to get it twisted together enough to get them back on, but I think it must have had a weak spot there. Overall, we are satisfied, but just be careful with them!Used these lights for Spring/Easter decorations because they are more pastel colored not Christmas colors.Very cool lights just as I was looking for! I just didn't like how they were put on the roll backwards as how most people install them.I keep Ordering these so that pretty much tells you I must like them and they work and do what they're supposed to. Plus finally the color is cobalt blue which is What I Like at night and is extremely hard to find Everybody says they have cobalt blue but when it comes it's just blue and after about a month of burning it's pretty much white, So far not these.Purchased these lights to hang in my kitchen for a Halloween birthday party. They are easy to hang, are very bright and work well. Had no issues with the lights being over the microwave or kitchen sink would definitely purchase againI bought 3500 of these lights for outdoor Holiday decorations. I wrapped the AC units in plastic with electrical tape so they would not be exposed to weather. The lights worked great until the first rain. After that, about a quarter of the lights either stopped working or worked intermittently. Upon closer inspection, I see that some of the strands were spliced at the factory and the splicing was not done well. On top of that, the strands of wire that connect all the lights is very thin and brittle. When I took all the lights down there were some kinks in the strands caused by placement in branches in trees and bushes outside. These kinks split and the wires broke, this happened on two of the eight strands I bought. I suspect I will have to repair this next year before using them again. Also, since you cannot connect them end-to-end means that you have to have one plug per strand which makes the logistics of getting power to the strands complicated. Overall these lights are very bright but the durability and quality is questionable.I love these lights the different modes are excellent and you can dim them or make them brighter with the touch of a button.Really finished off our gazebo.Boring all-on then all-off pattern only! Zero twinkle effect. These LED lights do not twinkle Independently at all. In other words, the entire string is either on or off (whether fading or on; the result is the same i.e. no twnkling).These are great! It's cute and adds the right amount of light for what I am looking for. In my opinion, the amount of light that emitted out from them were just perfect. I was amazed at how small the box/packaging was considering how long the lights came in. I will definitely purchase these again IF the lights last all winter long without burnouts or malfunctions. The price is great, too.I really love these lights (the 99 feet I received is amazing) but I received a faulty LED driver with this 33' order and the lights don't work properly. After plugging them to the other LED driver I received with the 99' batch, they worked fine.Great product but poor quality control?Stopped working during a rainy day. Tried drying out power adapter with no results and are no longer working. Would not consider the power adapter to be water/outdoor rated that is provided with LED string of lights.
