[2x] Item was shipped fast and promptly. The microscopes works as advertised. You will need to buy blank slides. The lcd screen works much better than standard eye pieces. It is very lightweight and does not take up much space in your home. Don't believe all the negative reviews about this scope. You can see all kinds of living organisms in one drop of pond water. The attached images are some kind of egg sack. (Not sure what it is) that I found in a drop of pond water. Photos were taken from the Pentaview. You can also record video. Comes with a 4 GB SD memory card.

[2x] This microscope is amazing, my 12 year old daughter was happy when she received it. It have an excellent performance to be an light equipment and practical. With my little daughter we are beggining in the science world and this product is a great tool. It coming with samples for start to use it.
Easy use, good packaging and fast delivery, is the best option according that price.

[Coarse] The digital camera and viewer are second to none. It is better than what is available to me in my science department. As to its limits, I can dimly make out fuzzy bacterial cells on a professionally prepared bacterial microscope slide - as one would expect for 400x without phase contrast or an oil immersion lense. The image quality for eukaryotic cells is crystal clear and outstanding. The batteries fit in the battery compartment just fine and the electric plug also works just fine. The light on the tetraview cannot penetrate a leaf but I have worked with professional scopes whose lighting is powerful enough to penetrate a leaf without further sectioning to make it thinner. Overall, it seems to be a very good product that is professional grade in most of its components and optics. The digital components are outstanding. The light is sufficient, but I think some professional scopes have a more powerful light. Some of the parts, such as the little metal arm that holds a slide in place, seem a little bit more flimsy than a professional scope. I would still rate this scope very highly and it certainly exceeded my expectations.

[Battery] This was just my son wanted. Great screen resolution and the ability to capture photos. I would recommend this to any budding scientist.

[20x] It fits to then perfection into the daily routine of the Surgical Pathology Service of the Hospital Provincial Eduardo Castro Rendon.

[20x] We researched this product carefully, watched videos, and decided it would answer our needs. We are a Rock Club that studies the minerals we collect, and we also feature a Kids Booth at our Annual Show. This microscope is great for both venues. The fact that you can see what you are looking at on a big screen TV is an absolute plus. Everyone can see the specimen that is being examined. Picture is awesome. 
The cords keep you tethered pretty close to any screen so we invested in a couple adapters, extension cord, and an HDMI cord to free up the action. Works perfect.

[2x] This is an excellent field microscope. It's easy to use, the images are clear and the unit seems to be built very well. At this point I can find nothing to list on the downside; only time will tell.

[20x] I found very easy to use. simple features make it easy to focus. It's fairly sturdy, and extremely flexible.
