See a whole new world
By Glenn R. Kangiser
I use this for checking gold ore samples in the field as well as general looking at the microscopic world.

The LED light is great but I did have one problem. I left it on and the next time I tried to use it the light would not work…. dead batteries. Unfortunately the batteries cost near $5 each times 3= $15.

All is not lost however. The Rite Aid (Pharmacy) had hearing aid batteries that, while not the same type as the listed required batteries, were the same physical size but were 1.4 volts instead of 1.5. I did not feel that this would be an issue and decided to try it. They worked just fine and were $16 for 24 of them, so about $.67 each. Much better and I now have 8 changes in case I forget to turn it off again.

The replacement type I found was Size 312, hearing aid batteries.

Nice bit of kit.
By Dietz
The Carson MM-200 is a fantastic bit of equipment. The size is just slightly larger than what the photo shows on the product page. It is TINY!! The product quality, however, is excellent. It has a great LED lamp, and I haven’t had it long enough to comment on the battery life. It is WAY better than the previous ones I have owned with regular little bulbs which gives everything an orange hue, or the LED ones which are flimsy as heck.

I use it for various things: from checking out small bug-things on plants to fine details on stamps or even just my arm (for a laugh!). It really is quite versatile and has great magnification!

Now for the bad. It is TINY!!! The knobs are a bit fiddly specially when you’re using one hand and need to adjust the focus. The other pocket scopes I have tried usually have a larger gripping area and larger dials. Hopefully it will loosen up with some use.

Other than its size (which I do very much like for convenience, but is a bit fiddly), it is a great scope.

A good alternative, for those with waning coordination, might be a pocket USB microscope, or even one of the larger varieties from Carson!

Save Your Money
By Tat – Ace
I bought this for checking edges on barber’s razors, also known as straight razors. I sharpen them and use them for shaving. The scope is a pain to focus as other reviewers have mentioned and in my opinion the optics are inferior. There is a learning curve with using the tool because of the inverted image and the difficulty in focusing while maintaining the view of the object. Once that is overcome the optical quality falls short. A 30x eye loupe from Widget Supply was a far better investment for my purposes. You pays your money and you takes your chances. In this instance I ended up a loser. So for me it was a waste of money. Your mileage may vary.
