Very happy, purchased for hunting after reading alot of online reviewa for earlier models. Focussing is easy and can be done with one finger, through clarity is excellent and bright, a little distortion right on the edge of view but very evenly balanced through out. Have uses them at night aswell for checking out the stars... And even inside the house to focus on the dust on the wall. Good solid build and comes with a carry case. I can't comment on the test of time, but a lifetime warranty should cover that.
