Review on Jiusion 2MP USB Digital Microscope | Portable Endoscope Camera with 8 LEDs | 40-1000X Magnification | Aluminum Alloy Stand | OTG Android, Mac, Windows 7/8/10, Linux Compatible by Nathan Pintac

Great microscope and stand for easy focusing. I turned the stand sideways to focus horizontally on the platter "needles" which were face up. I can inspect the tips and can actually see the chiseled edges of the different diamond cuts. It doesn't reach microbial scales, but for pen tips smaller than 1 mil (less than 25 microns), it works great and is very cheap!
