We have had these for a month, and they are working very well. The length was just right to wrap around our backyard pergola, we use the spring clip they came with to attach it. These lights have so many great features: they turn themselves off at night so theres no wasted energy and theres no flickering lights when it has run low. These bulbs are made very well and even though the price was higher than others I saw, I think the quality makes it a great buy. I will definitely be a repeat customer.
