These are the best binoculars I have ever used. The image is so clear at long distances (and extreme close-ups), I couldn't believe binoculars could work so well. These feel very sturdy and well made, but are also light weight compared to other brands. They're incredibly easy to adjust, and I have just zero complaints about the binoculars themselves. My husband did say he wishes the strap were longer and more cushioned, but I prefer to rate the product itself, not the attachments (which you can easily replace). The lens covers are a nice rubber material and can be attached to the strap.
