Bought for 8-year-old, and I ended up messing with it for hours. Things look fine on the 2" display, but after loading the images onto a computer I was amazed at the clarity of the images and videos.
I did not try the suggested software for viewing directly on a computer via usb, though.

We were able to view some microbes (paramecium?) in a drop of water. Didn't expect that.

If you buy this, the AA battery box on the bottom of the stand is for the backlight. The microscope itself (and it's main LED lights) is powered by an internal battery that is re-chargeable. This took me a few minutes to figure out.

Things that could have been better:

The instructions were a bit vague. There are clear plastic pieces included that were not mentioned in the instructions, although I think there are meant to hold specimens when using just the eyepiece without the stand.
No slides included.
The lens assembly doesn't extend far enough down to view something at the highest magnification if it is resting on the bottom (where the AA battery powered backlight and slide holder is). I used the transparent lens cover inverted in order to lift things close enough to the lens in order to view things like microbes. Also, I couldn't seem to turn off the backlight, and had to remove the batteries to turn the backlight off.

Lastly, the microscope was packed loosely in it's box, and although somewhat confined by a molded plastic insert, other parts were just flopping around in there.

Well worth the $67 I paid for it, and honestly I would have expected it to cost much more. Despite the few things mentioned, I would definitely recommend it, especially for young people.
