After 3 years of use
We have other Vortex binoculars of 8x power, but we have not used them since we got this .
It's very nice to have that extra bit of reach. We may even get higher power one the next time we visit EO for stargazing.
We use these binoculars everyday for birding and watching wild life. They work well in heat and cold of all 4 seasons, and in any weather.
The close focus of 5' also allows us to view flowers and insects, too. Plus, observing wild life at dawn or dusk was easy.
We are very content with the Diamondbacks.
PS: My wife dropped her binoculars while hiking and the Vortex warranty/repair service was fantastic.
