I am an individual who is visually impaired, and I rely on monoculars to read signs, signals, menus, cell phones, and to look at scenery. I use them at the boundaries of their functionality--difficult lighting, close focus, etc, and this one seems like a great monocular for people who want to look at distant objects with large magnification, but not some of the other things like close focus or low light conditions. The Basics: The monocular is the same size as a stanrard 10-power monocular. There are two dials to adjust--one is the focus and the other is the zoom mechanism. You'll notice once you hack open the plastic shield packaging that the monocular comes with a carrying case, a short (4 inches or so) strap, and a lens cleaning cloth. When you look through the monocular, the focus is relatively easy to manipulate, but it really requires 2 hands to operate this unit because the focus and the zoom are in places where the human hand cannot manipulate them without a second hand to hold the monocular steady. Also, you should be used to looking through these monoculars, as the 30x rating means that you'll need a steady hand at full magnification. I do find the unit to be visually attractive, and there is a mount for a tripod. The Good: Small size and lite weight makes this a great scope for birdwatching or camping. If you've got a steady hand, this will be a great buy. The image is reasonably bright, but if you want real brightness from a 30x scope, you're going to have to get something a lot larger than a 21mm objective lens--try 50 or 100mm. But that'll run you hundreds of dollars and a lot heavier. This could fit awkwardly into a shirt pocket. The image will get a little darker as you zoom it in, but the closest focus distance of about 10 feet seems to work at any magnification setting, which is nice. The Bad: The strap is short--usually people like to put these things around their necks, but that will not be possible with this hand-sized strap. The picture quality is great for a blind person, but if you are a picky person or somebody looking for a top-notch unit, then you won't even be reading this. Also, I will not use this for many operations because I need the real close focus of about 12 inches, and this gets only as close as 10 feet. And as I said, the focus and zoom are hard to manipulate with a single hand, so you'll need a free hand to make things easier. Overall: A good inezpensive buy. Nice for the car or backpack, but not for stargazing as the objective lens is too small. If you're in the market for an inexpensive, small, yet powerful monocular or binocular, I'd recommend the CARSON 20-80x25 zoom binocular. Somobody stole my pair (who steals from the blind!), but I loved those for the Chicago Symphony Orchestra when I saw Yo-Yo-Ma there in 2005. Also, find a tiny tripod to make your life easier in those situations.
