400X Magnification World's Smallest Smartphone Microscope For Cells, Jewellery, Watches, Photography, Mechanics - Includes Brackets - Easily Share Media with the Nurugo Application

Very cool product. The lighting system is ingenious. Look at my amazing USB cable! For those of you who say the screen is dark, you've probably just got the lens on the wrong way (the lighting apparatus needs to be on top of your phone's flash)

Blew my mind with the kind of zoom this one achieved... The photos look crisp and well detailed... this one is basically to examine flat slides... takes a bit of getting used to for observing 3d objects... but still for the size and price of this lil dynamite, i’ll say its a must buy...

The lens itself is great, but as some other reviews mentioned the housings are finnicky. Keeping the clear housing in place is annoying but manageable; the real problem is the black housings. It is incredibly difficult to pop the lens out of the black housings. I recently got a new phone and was trying out the black housings to see if they would, since they seem a bit more precise. After a lot of effort and being very careful, I was unable to get the lens out of the housing without cracking the plastic body open where the front and back meet on one side. Really frustrating to have possibly ruines a $75 lens just because the housings provided suck so much.

As claimed by the manufacturers, it is a good device and performs.

The microscope requires the lower half to sit over the phone's camera light, and the lens half over the camera lens. The microscope utilizes the phone's camera light to provide illumination around its own lens. The mounting brackets provided do not allow the microscope lens to align properly over the Motorola G Power's light and camera lens because the bracket does not sit firmly and is easily jarred out of position. This makes it very difficult for the focus-adjustment tool to be used, since the least movement of the focus adjust moves the microscope. Very frustrating!
