Review on Oxbird50X-2000X HD USB Microscope for Adults - Digital Microscope for Android Phones (non-iOS iPhone), Mac & Windows 7/8/10 Compatible by Mark Powell

First image is Oxbird 2000x directly on the supplied test reticle, second image is of a very old db power 300x USB microscope (which looks almost identical in appearance and costs about the same), also directly opposite the same one designated crosshairs. software provided by oxbird, the settings for each image are identical. I'm sending Ochsenvogel back! I will try other inexpensive USB oscilloscopes until I find one that beats the db power scope in magnification and resolution. It wasn't like that.
