Apexel Macro 12-24X Lens attachment for Smartphones ( Photo Samples)
I got this lens from Aliexpress (link). Here is the link for Amazon. The build quality is good, the lens does have a coating as advertised. I just use the 12X one as 24X makes it non practical as we have to be extremely close to the subject. Be sure to remove the phone case. I would suggest to use it in good lighting conditions.
