This is simply the best tiny binocular that you can buy for under $20. Images are crispy, it is very easy to focus. You can also compensate the difference of vision between your eyes because you can rotate the right eyepiece. Although diameter is only 21mm, I've got better images than those that I get with another more expensive binos I have (they are 10x25). Because they are 8x21, images are very stable (when magnification goes higher, for example 10x or 12x it is very easy that with a little movement of your hands the image shakes). The material is also very comfortable and provides a very good grip. With daylight, it performs as well as my 8x42 does, this last being heavier. With less light, images are very acceptable, considering the small objective (21mm). They are also extremely light so you can take them always with you. Very good binoculars. 100% recommended. 5 stars

I needed a pair of binoculars for bird watching. These were a cheap option with a known brand name. They serve their function well, and you cannot beat the price. 5 stars

I am very pleased with this purchase. Looking thru it is very clear and easy to see. Also love the small style and case it comes with. 5 stars
