Spend more or pass
Binoculars feel okay for the price. I would not compare these to any name brand or even higher priced “no name” brands. They cost (today) ~$12 a pair. While I can get a clear image on each individual scope, I can’t get a “single” image. No matter how much I adjust, I keep getting a double image - so quality is variable. Comes in a good enough carrying case and the grip is 3/5 - not bad, but nothing intentionally making them grippy. I got these for a bird related non-profit where we have a tight budget. These are used as loaners during walks. Last year, I got a different brand for about the same cost, and the difference in quality between the two is extraordinary. The other cheap no name brand was able to be dialed in just like a pair of Nikons - just without the stellar image quality, low light performance, etc, but definitely good enough for a kick around pair without risk of damage. The dials on these BINs are also extremely hard to adjust, and for kids and elderly, they’re a no go. I’ll be returning 13 pairs.
