It's simple and easy to use and great that's it's rechargeable with built-in battery

The filter is nice and flat, the glass is impeccable. The screw thread fits perfectly into the lens thread and the lens cap grips easily. I could not determine any distortion of the colors in comparison shots. I use it to protect the front lens; I hope he lives up to his intended task.

I purchased this microscope so I can be able to take a close look at coins. It's a pretty good microscope for the money and I love that it has a rechargeable battery. The battery seems to last quite a while even with the light on and screen using up power.

Pros:
rechargeable battery
Nice clear screen
Bright light
Adjustable zoom
Lightweight

Cons:
Resolution is not so great in my opinion. Good enough but not great.
Fine focus knob isn't really fine.
Light adjustment isn't that great. It's either too bright or not bright enough.

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.

The 10,000mAh rechargeable battery is a powerhouse, supporting up to 7 hours of continuous work. This, coupled with a 1/3 CMOS high-resolution sensor, ensures that inspections in low-light conditions are clear and effective.

This range finder does everything a $399 brand name can and is just as accurate. It has all the features you would ever need and has a rechargeable, built-in lithium battery that seems to last forever.

The best quality is the rechargeable battery, which unlike other batteries I've had, holds the charge so I have to keep changing batteries after an hour of use. Image quality is great, as is the number of display modes and options.
