It's been 2 weeks. So far the lenses have served me very well. I use the macro lens more often. However, I did use the wide angle lens for some selfies. It gives kinda fish-eye type look on the borders, but that's normal for lenses like these. Photography is my hobby and using these lenses with my iPhone has made the task so much easier. With the macro lens, it's possible to get super-close to objects. You'll also get a really shallow depth of field, even better than the portrait mode of iPhone 7 plus.
The build quality is excellent. The lens body is made of metal, probably aluminum. The glasses are crystal clear and are certainly of high quality.
The rechargeable LED light is quite bright, although I don't know how useful it is, as personally, I haven't found a situation to use that.
The lens carrying case is great, makes it easier to just throw it in my backpack. Another upside is the LifeTime warranty!
