Summary: Small enough, easy to use, stays in focus, the zoom is just right - and all for about $40: a good buy, so much so that I got two. One minor, but puzzling complaint: only one hook, so cannot use the usual neck strap.
Summary: I purchased these binoculars due to the zoom and Carson's great warranty. The binoculars were defective as I could not make it so I could see only one circle when looking through the eyepiece. I contacted Carson multiple times over a two week period to get a replacement pair. Each time customer service informed me the person in charge of warrantys was out. After leaving multiple messages I have never received a call back after several weeks.
Summary: I have no opinion about how these mini binoculars compare to others in it's class. I was unaware of how small these really are. I could not get comfortable with the physical size of these binoculars and feel that unless you really know what you want these are a good candidate for local purchase so that you are comfortable with the size and features. I find Amazon a great source for many of my purchases, it just didn't work out this time.
Summary: Pros: Compact & lightweight (fits in your palm). Zoom feature from 5-15x. Overall good durability design. Walmart price vs. MSRP. Ship to Store is quick, convenient & saves $$. Cons: Focus is not always precise (sometimes requires tweaking back and forth to attain best focus). Case is a low quality plastic pouch. (However, it has a small profile, so it can easily fit in a purse or cargo type pocket, or be attached to a belt via its case belt loop.
Summary: I received these about a month ago and can not believe how very functional these Binocs have been. I have been using Binocs all my life(past 60) and the 517 lives up to the best in performance . I grew up in a Sporting Goods Retailer family and had an opportunity to use a lot of different products over the years and -for the price -really at any price -these fall into the top ten of my favorites.Compact and easy to use,these fit in my coat pocket.They are very light...
