This sturdy binoculars are absolutely amazing for using outdoors as well as inside large places, such as concert halls. I use mine to watch the wildlife in my backyard and they proved to be so easily adjusted and are very light weight so your as don't get really tired after holding them up for a few mins. The handy carrying case was a bonus because I wasn't expecting that but it keeps the binoculars from getting damaged when I'm not using them. This product is well worth the money spent for it! Highly recommend!
