If they had suggested this was a good microscope for anything other than flat stuff, I would have given it 4 stars. It is a very nice microscope at this price point, but it's not the best thing if you want to look at non-flat stuff. I tend to use my microscope with electronics stuff. Reading numbers off chips, and stuff like that, and it is fine for doing that task.

The included memory card is real (it doesn't clam it's bigger than it really is), and I did a proper test on it. Being able to use this microscope, and take pictures, without being tied to a computer is awesome. And if you do want to connect it to your computer, and use it like a webcam, you can do that too, so you get the best of both worlds. I didn't pay real close attention to how long the battery lasted, for how long I used it, but my feeling is it should have lasted longer than it did. I may pop open the case, and see about replacing the battery with a bigger one.

My only real complaint, is I feel it should have more up/down control. My other USB microscope, has a knob that will travel the entire length of it's support pole. And I don't like that it has two knobs, one to adjust it, and one to lock it. I feel it should have had one knob, and enough friction to keep it where you set it, but that may not be as easy to do as I think it is, with the additional weight of the display. And while I do wish this aspect was different, I'm not going to take off any stars, because it does the job, and is fine for looking at flat things, as the listing says.
