Our Son loves it and it works so well for him

It is a lower-end biological microscope, but it is perfectly adequate for education use and even some less critical real biological work. It is certainly much better than most cheap educational microscopes or the abysmal toy ones.The hardware is definitely a little dated in the sense the LCD display resolution is low and the illumination is a bit dim for the highest magnifications, it uses a mini-B USB connector, etc. The saved files are fine, but focus perfection would be easier with a bit more resolution on the display device. I like that the screen stylus has a mounting spot on the top of the body. The top-side illuminator is basically useless, but it is rarely useful anyway. The stage backlash is a bit annoying, but you get used to it. The focus vernier on my unit was tight, no sign of the slippage some comments mention, maybe even too tight really, I suspect it can be adjusted but I haven't tried yet. I don't love the colour balance options especially when combined with the colour filter wheel. The aperture options are OK, the condenser isn't otherwise adjustable. I suspect it doesn't support modern larger capacity SD cards but that isn't a bit deal. I haven't tried using the battery supply or USB data options.The carrying case and dust cover are actually quite good for the price I didn't expect them at all.I have a much fancier real biological microscope which is obviously much better technically, but for a lot of stuff this scope is great. All in all I am glad I purchased it, I can take it in the field with me and not worry too much if I wreck it.
