Great value

I've been looking for lightweight binoculars to carry on hikes, because my 42mm Leicas are too much sometimes. These are just what I've been looking for. Eyeglass wearers will appreciate the good eye relief, and the new and improved coatings control glare like far more expensive binos. I liked these so much I bought the Pentax 7x32 model as well. For the price, these binoculars are a steal.

Great Optics

Optics are very clear and the binoculars are small and compact. I would still not recommend trying to use this with glasses on even though the eye relief is longer than many other binoculars.

Love these binoculars

Love these binoculars. Great for watching the red-tailed hawks in the trees of the park across the street. They are also great for taking to the ballet, small enough to fit in my purse, unobtrusive, and the level of detail is phenomenal. So glad I got these for myself.

A good thing in a small package

Binocular arrived well protected by its packaging. Light weight and well made and seems to be very good quality. It's very useful and easy to use for certain purposes, which is why I bought it. It won't replace a larger, good quality binocular but that's not what it's for. Shipping was free and very quick. It fills a need for a very nice, small, casual use tool that won't weigh a person down.

Waiting to Use

This was given as a gift to my daughter mainly to watch her daughter perform in Cheer competitions. Will not use until the 17 Jan. When she first opened the gift I thought it looked cheap and so did she. Told her the cost and we agreed it looked like a WalMart or Target special.. Hope it performs better than it looks.

So so

The visión is pretty good. The problem is the strap. It’s nearly impossible to attach properly, and the instructions do not help at all.

Very happy with the 8x25

Nice compact high quality binoculars. Great product and value. We got the 8x25 and are happy with this field of view and light gathering. Keep in mind the higher magnification will magnify movement of the binoculars so we got 8x
