1. I bought this microscope some 3 months ago. The mount is much more rigid and satisfactory than the cheaper microscopes that are available. 2. The carriage is a slack fit on the vertical column. Tightening the lock screw moves the microscope body and throws the image out of focus. 3. The specifications quoted by the manufacturer are questiuonable. Using the (very convenient) screen that is part of the microscope, the max magnification is 14x to 56x (using the 4x "digital zoom") and the working distance is only 25mm. If you set the working distance to a more convenient 50mm, then the magnification range available is 5x to 20x. If you set the microscope to the top of its column, the working distance is 122mm, but the magnification range is 2x to 8x. 4. The image on a large HDMI monitor is spectacular, but the monitor has to have the same aspect ratio as the microscope's little screen, else the image will be compressed or stretched. There appears to be no way of correcting that. 5. The specifications claim a magnification of up to 300x. To achieve that, you will need an HDMI screen 350mm wide, you will need to hold your eye as close to the the big screen as you would to the microscope's little screen, you will have to put up with a working distance of 25 mm, and use the full 4x digital zoom. 6. I was able to use the USB connection on one Windows XP computer with AmCap imaging software, but unable to get it to work on two Windows 7 computers, with AmCap, Oasis nor Debut. A search of the web showed that many people were having trouble with the USB connection. 7. The distance between the optical axis and the base of the column is about 65mm, which limits the ability to work with large circuit boards. This can be overcome by turning the base upside down, clamping it to a bookshelf then re-attaching the microscope. Details can be found on the web. 8. To use the microscope, you need a USB cable to power the microscope, a second USB cable to power the lights, plus an HDMI cable if using an external monitor. On a crowded workbench, they are a pain. At the very least, the two USB cables could have been combined. Having said all that, it IS a useful instrument, it is far better than the cheap non-rigid plastic units available, but with a bit more care in the machining and design it could be very much better.
