    5Excellent binoculars
    By CB611
    This is exactly what I wanted when I ordered these. I live in Maui and got these for watching whales off of my lanai Great resolution the 40 X Power is great for Viewing whales 10 miles or more away when I look over the ocean with my naked eye I see nothing, I looked through the Barska jumbo it is whale soup everybody has been extremely impressed with the quality of the viewing experience my wife even enjoys using these throughout the day. You definitely want to have these on a tripod focusing each side separately is a little challenging however the result is excellent The images are bright and crisp with great detail.

    2Quality control lacking ...
    By David L. Diller
    Based on Amazon reviews, I bought these for our beach home in Mexico. I really wanted these to work, but sadly, didn't have the same positive experience as the other five star reviews. The left eyepiece was stuck, preventing focusing of that side. Removing the eyepiece revealed a piece of rubber O ring had broken and fallen into binoculars cavity. Removed the offending O ring rubber, but still unable to smoothly swap eyepieces and focusing was rough, never able to focus left side. Right side focused OK, but not very bright. Returning them for refund.
