The good:1) Very light. This makes them an excellent choice as an affordable hiking/backpacking binocular.2) Decent optics. Images were bright and sharp (in one eye, see below). Low chromatic aberration, decent stray light and veiling glare control. Very minimal field distortion. Sharp almost edge to edge. Nice looking coatings on all the surfaces I could easily see.3) Single hinge design is simple, rigid, and robust, more so than some competing dual-hinge designs.4) Plastic bodies are generally a bit more shock resistant than metal bodies, and won't deform from impacts, features I like.The mediocre:1) Somewhat bulky for a compact binocular. While the offset sing-hinge design goes a long way towards making these fold into a compact package, it's noticeably bulkier than dual hinge designs... But not as bulky as symmetrical single hinge designs. It's a very reasonable trade-off, though.2) The case is tight. If you like to carry compact binos on a belt (a common location for binos while backpacking), they're a bit fiddly to get in and out of the case. A teeny bit bigger case would have completely solved the issue.2) The hinge on my sample was a little loose, enough so that extra care had to be used while observing in order to maintain the correct inter-pupillary distance.The bad (and this is a biggy):1) The diopter range is very small. (In case you're not familiar, the binocular diopter allows the observer to slightly adjust the focus of the right side independently of the left side. Most people have a slight difference in how their right and left eyes focus. Out of the dozens of binoculars I've used, I've never found one that didn't have more than enough adjustment for me to get a sharp focus through both sides of the bino at the same time. The Orros, sadly, didn't have enough range, which didn't allow me to get a sharp focus through both eyes at the same time. Because of this, they had to be returned.2) Minimal eye relief (This is the distance your eye has to be from the eyepiece lenses for you to see the entire available field of view; if your eye is too close, you don't see the entire image, if your eye is too far, you see the entire view, but surrounded by excess dark field, sort of like looking through pipe.) This is only a big deal if you wear glasses (I don't). However, because these binoculars have such minimal diopter range (see above), you couldn't use them with glasses that might otherwise correct the issue. Odd optical and mechanic choice design choice here.These would get solid 4 or maybe a shaky 5 stars if it weren't for the lack of diopter range. If you know ahead of time that you use very minimal diopter adjustment when you use binos, these would be a top choice in this price range. If you generally like to share binoculars with other people, I'd go with something else.
