Pocket Mobile Microscope 20x - 400x Magnification Educational Toy Portable Microscope for All Smartphone No Need for Batteries (Black)

Minus one ⭐ because it is tricky to attach to the camera lens well. Once you get it tuned though it is a lot of fun. Works best on smooth surfaces such as countertops and tables. I show three photos for example: a quartz countertop, some fabric, and eggplant skin. I think the 400x magnification is an overestimate, but the ability to save photos and videos right to your phone is a HUGE value. Would recommend to a friend.

The media could not be loaded.  It has a clear picture (if you can illuminte it)Lenses are clear and sharp... But it has no light. On my phone the microscope covers the light and so it is dark. Frustrating.And the glue to hold it on my phone is slightly stickier than saliva. Juggling the micro, the phone, and a separare source of light made for an expensively uncomfortable time. I suppose if I ever want to spend time and money getting better glue and some viable source of light it might be cool.
