Title: Inexpensive, but not good quality
Review: Probably the least expensive 10-30 zoom binoculars you can find. However, the quality is lacking. The problem with these is they are very hard to focus, and the focus wheel is very sensitive. A little nudge sets them out of focus, and you need to re-focus again. That means that if you adjust the distance between view lenses to set for distance between your eyes, the focus is lost. And focusing them is hard - it has to be just right. A little bitt off, and focus is lost. I do not recommend this pair. I am returning mine, and using a Celestron UpClose zoom binoculars instead. Just a little more expensive, but same zoom numbers and lense sizes. Also, Celestron has a Field of vivew of 4.1 degrees, compared to this item's 3.8 or 3.9. Buy at your own risk.
