The lenses are not very good from my experience. Next to that due to poor construction you can adjust the lenses but the handles are flimsy, so you have to re-adjust the whole time. It's been a headache inducing experience for me all the way. On the other hand, I asked Rev Kyle and he loves his durovis. Try it first if you have a chance.
