UM02 USB Digital Microscope with Steel Stand and Measurement Function for PC and Android OTG Smart Phones

Simple to use if all you want to do is see an object up close and snap a picture.Difficult to use if you want to use the included software for measuring and comparing images.USB connection intermittently goes in and out. User manual clearly written by someone who did NOThave a command of the English language. Broken English and often times instructions that don'tmake sense. Achieving image stability is difficult. Light and focus tend to slightly wonderon it's own. Probably has more to do with the cheap controls for these functions. I haven'tbeen able to figure out how to measure on a captured, stored image yet. Can only measure onthe live image. If the software worked better, then the value would be there for this product.Without the software functioning as well as I expected - it's overpriced.

I have been using the ViTiny UM02 in a professional lab setting for several years now; inspecting, among other things, the integrity of circuit board solder joints used in military applications (and a whole lot more). I simply CAN'T afford to be wrong when I say PASS or FAIL on parts that can mean the difference between life and death to their users. I find this product as good or better than some scopes costing 10-times more. This is seriously one of the best digital scopes I have ever used. After spending weeks studying various USB scopes on the market, and pretty much deciding the ViTiny UM02 might be the one to buy; I came across Dr. Roger L. Mccarthy's review on Amazon dated June 18, 2011. His review convinced me I was on the right track in selecting a relatively inexpensive scope with a high effectivity factor for performing important lab work in a chaotic environment where "things" get knocked around a lot and too often broken. I needed a scope that was superbly sharp and easy to use, but one that I would not need to obsess over if it were damaged. The ViTiny UM02 was it, and I have never been disappoint by my choice. Also, in all this time, it has stood up to the challenges of rough handling while always maintaining its precision. I highly recommend this scope for industrial, school, and personal/hobby use. Incidentally, I highly recommend that you read Dr. Mccarthy's review of this product on Amazon, and that you also check out all of his remarks since 2006 by clicking on his name at the top of his review.

Nice little web cam. the best part is the variable zoom. There also built in lights are also helpful, but can wash out the image a bit. The built in light also have a variable brightness dial on the side, very convenient. We did use the included software, so I can't comment on that, we used Picasa to take screen shots.

Ordered this web-cam on the recommendations of others here. Some observations:1) The software that Oasis Scientific makes available on its web-site for this camera only allows taking pictures of up to 640x480 pixels. That's 0.3MP, not the advertised 2MP resolution. I tried the alternatives they linked to also (Yawcam, among others), similar resolutions ensued. For fun, I tried out Photobooth and the Mixscope on the Mac, same results as on Windows, i.e. no resolution higher than 640x480 was selectable in any of these programs.Based on my earlier two-star review, I was contacted by Michael at Oasis Scientific (OS). He informed me that in order to get the full 2MP that one has to install the UM-CAM software off the enclosed mini-CD. Additionally, the UM-CAM software also enables other functionalities like distance measurement, etc. That's good to know but I wonder why the UM-CAM software (or at least the enabling 2MP drivers) is/are not available on the OS web site. Many laptop users have slot-loading CD drives that cannot use mini-CDs after all. For that matter, why does the web-cam install without the need for drivers if it needs a driver to achieve full functionality? One commenter found the vitiny software on the OEM web site, so I wonder why OS doesn't link to said software instead of alternatives that do not reach the 2MP advertised.2) The stand is great for use as a web-cam: It's very pretty, made of clear polycarbonate, with solid, wide feet and a nice set of rubbery grippers to hold the camera securely. However, these pretty feet get in the way of taking close-ups with the microscope. While one can devise many ways to hold the vitiny with a standard microscope holder, the vitinys rectangular body is not as easy to mount as a more standard round microscope.3) The LEDs add a lot glare because their light is not very diffuse and/or they are mounted too close to the lens. Thankfully, the LED brightness adjustment works great. Once one dials down the brightness of the LEDs a lot and adds a lot of ambient light, the pictures come out a lot clearer. Plus, given how blue the light of the LEDs is, ambient light adds more natural color to whatever is being photographed. For chip-identification photography, I found that illuminating the chip with an angled light-source from the side added sufficient contrast to highlight the chip markings.I unfortunately had already requested an Amazon return by the time Michael contacted me regarding the requirement to use UM-CAM software. However, OS could do a better job of supporting their product. Ideally, they would post the latest version of the UM-CAM software on their web-site for download. They should also mention in their Amazon listing that the install software comes on a mini-CD and that the camera can only achieve its advertised specifications with the use of UM-CAM even if it behaves like a plug-and-play web-cam out of the box.I finally settled on the  Supereyes 500X 5MP USB Microscope and Stand . This camera is recognized by Windows automatically at its native resolution and can be accessed through windows explorer. The supereyes stand is a basic but usable microscope stand, allowing me to take pictures with a wide variety of magnifications. Additionally, the Supereyes LED array features at least one yellow LED to somewhat ameliorate the blue shift that the built-in LEDs build into each image. Like the ViTiny, one is best off creating great ambient light conditions rather than relying on the the built-in LED arrays.As I see it, the vitiny 02 and its stand are meant for a different application, i.e. web-cam use with the occasional close-up (though a good one!). All that said, I thought it was great that Michael contacted me regarding my product issues. Accordingly, I have raised my review by one star to three stars.

This product could be good for some uses, but I needed something to take close up pictures of old coins to sell. This just doesn't cut it for that. It's not like anything else. Focussing is a little difficult, because there is a time lag from where you position the camera, and when the picture becomes clear on the computer screen. The picture taking capability is good, though.

I have buying the various inexpensive webcam digital microscopes that you find around. They are cheap, and sort of crappy (optics, structure, functions, bugs). But this microscope is surprisingly well put together. The little stand is actually made of steel, it's pretty sturdy. Focus and light controls as manual, and on the device itself, so you don't have to fight autofocus or too much brightness from the light. I worked off-the-box on Ubuntu (10.4, an old version!). I am happy with it.

Works ok for what I need but the measurement functions are not what I was expecting. It needs to be calibrated every use at the correct distance from the camera for the measurments to be accurate. The user interface could be better - any zoom level other than "normal" (looks like about 640x480 - entire window is 1/4 of my screen size) makes the image larger but makes the measurement icons disappear.
