ESSLNB Astronomy Binoculars - 20x80 for Adults, Outdoor Waterproof Binoculars for Bird Watching, Travel and Stargazing with Tripod Adapter and Carrying Bag

I'm not an expert, but I'm very happy with the visual quality these binoculars have. Granted, I don't have another pair to compare them too, but they seem to be very sharp and the image is very bright. The eye relief works well for me too and I'm a 68 yo who wears glasses (I use the binoculars without the glasses). Do note that these are NOT light. I use them in conjunction with a tripod. That stabilizes the binoculars and makes for enjoyable viewing. All in all I'm very pleased with my purchase and I wouldn't hesitate to buy these again, should the need ever arise.

Well, I worked with the finest cameras all my life, so I did not expect much from these binoculars however, optics in photographic lenses in the past 3 years have gone through a revolution and I thought maybe these binoculars would benefit as part of the overall improvement in lenses. They did and are great for the money without exaggeration. Optically, except for outer field chromatic aberrations, these are as sharp as 2K$ binoculars in the center field with excellent color. At a distance of 200ft. , on cloudy day, 3/16" high lettering on a security tag is razor sharp . I have these on an expensive tripod with a 3" dia. ball head. These binoculars are mechanically perfect, smooth with just right resistance, great fitted case, quality coating on all optics, bright with VG contrast, fitted lens caps that work, excellent engineering and balance , flawless workmanship and great looking with quality materials used throughout. 9.0 rating for this sample I purchased here on Amazon. I purchased these because I could not find any actual reviews about this particular model on line. Very pleased now. Cannot tell how they will take abuse rain and weather however, I do not abuse or drop my lenses ( some cost 4k). I cannot comment on overall quality control of this company since I am not familiar with its products. P.S. the lenses are not bright red as depicted.... light orange red . Just looked at full moon and craters on edge are amazing like mountains in 3D.

I'm not impressed with these binoculars. I'm way past that. They blew me away!My first look through these binoculars was a few minutes ago after the delivery. Looked out at some distant trees and could see bees flying around a hive. Crystal clear images.I bought these for watching aquatic life and a few celestial objects because the price was right.These are light and easy to carry in one hand.They feel well built and seem to perform as well as my old Celestron 80mm×20 astronomy binoculars. Those were very heavy but I liked them.I'd even recommend these binoculars for kids.

I think for the price these are very nice, used them once last night and they are sturdy and controls are smooth. There is only one adjustable diopter, description states there are 2 and the phone adapter shown in photos is not the one I received but I think I actually prefer the one that came with it.

I'm just love it

El producto llego en un buen embalaje y protegido. Tienen una muy buena resolución y definición. Me encuentro satisfecho con el producto. Gracias.

Way too heavy and not as clear as I hoped for when looking .

Sure, these can see very far, I can see the moons of Jupiter. But since you can't really hold these while looking, I would be better off with a telescope.The only advantage this has over a telescope is that it's easier to find things.
