I was tired of lugging on walks always a pair of binoculars, as there is quite little used compared to the walking time. That's why I've bought this monocular, because it is quite small and very light. I also find that it is easier for a spectacle wearer to focus through a monocular as through a binocular. The reason why I deducted a point is that it is not very easy with this device, to focus. Namely, there is no thread but the tube has to be changed by pushing or pulling. But with a little practice and turning slightly at the same time slight pressure or train that goes then.
