    Ok, but needed adjusting before use
    Overall Score
    Bought these as a birthday present and decided to test them before actually giving them away. Sure glad I did!

    On first use the image was doubled and blurred, I repeatedly went through the steps outlined in the instructions to focus correctly but nothing worked. Was very disappointed and considered returning them as faulty. However I did a quick search and found this to be a common problem. I managed to fix the double image by tightening two screens which sit under the rubberized skin near the eye pieces.

    Since then they have been ok to use but I still expected the image to be clearer and I thought they would have been more powerful (magnification wise). The recipient seems to like them though. These are used for terrestrial observing.
