I just received my XMCOSY Outdoor String Lights! I was pleasantly surprise the packaging and contents were in perfect condition. All the bulbs were installed making it easy to try them out right away. All the bulbs worked and were brighter that i envisioned. The design and manufacturing seem very well done! Also, the instructions were well printed, detailed and seem easy to follow. I'm going to download the fee IOS app and proceed with the installation. I like that you an remotely control the color, brightness, and pattern and even set up a timer schedule with the app.I'll write another review after i have them installed and i get to enjoy them.
