They are very good. Right now, a lot of people don't seem to understand the focus system. Fact: There is no focusing system. Reason: You are pre-focused. High quality sign. However, there are changes to the left and right eyeballs. This is because when you take off your glasses to look through them, you can basically choose your prescription (left and right) to see clearly. Giving them to someone else can also help them get used to their poor eyesight. a good thing. The eyeball correction is a good thing. Again, there's no focus control for both eyes together because that would be stupid. Oh, and the compass is pretty neat too. And no, there's no compass strap to wear around your neck because it's built-in. If you want the compass around your neck, put the binoculars around your neck and the compass is there. Update: I noticed that there is a difference in focus when looking at big things like cheerleaders and mountains. The thing is. You have a great depth of field. So you can adjust when changing large distances to get the sharpest focus. But usually you can see clearly enough without adjustment.
