The device arrived relatively quickly, considering it was shipped from China. The microscope is OK for an item costing $35. The stand is flimsy and I added 90g of weight to it so the setup would be more stable. Focusing is quite touchy; it works better to set the focus approximately, then move the microscope a little to refine the focus. Magnification greater than 250X or so is hard to achieve. There seems to be backlash in the focus mechanism. See a more full review with photos at https://polymath07.blogspot.com/2021/03/testing-usb-digital-microscope.html.
