[18 mm] I am impressed by these binos. Wide field of view, clear image, light weight, feels good in the hand. I have not looked through lots of brands, but these aren't leaving me wanting to get a different pair.

[Center] This is the perfect size and weight for a 8x32 binoculars with bright image. Ideal for traveling.

[42 mm] I purchased this monocular primarily for stargazing. I have looked around the landscape too. The optics are just that, great. I can't see any limitations between my eyes and the atmosphere. The field is flat to the edges, judged by stars. There is slight brightness variation at the edge barely noticeable when looking at the light polluted sky.
The whole device feels small and light. It easily fits in a pocket. I can hold it in one hand no problem. The problem is to hold it with two hands when I want to minimize shaking. I wish they made a bigger model, like 12x60 or so.

Focusing mechanism is smooth. The eyepiece is comfortable. The smaller, eyepiece cap is rather loose, bound to be lost some day. The larger one is tighter and there is another one in the box with secure attachment. Included carry strap is weird.

[Center] The Opticron 10x42 DBA VHD+ monocular is a bit larger and heavier---more expensive too---than other handheld scopes, but the view is really unparalleled in terms of field-of-view and sharp definition; and the device is a real pleasure to use. My only complaints are that, once the objective lenscap is on, the scope fits too tightly into the belt-looped case; the eyepiece cap has to be secured somehow; and the rotating, elevating eyepiece is a little too free in its motion. In terms of sharp optics, though, this monocular is a real champ. (Why B&H sends a free binocular harness out with this monocular, I could not tell you.)

[Roof] I can't say enough good things about these binoculars. I spent a lot of time researching different options and I feel that I made the right choice.
They are exceptionally well made and the image is clear and sharp across the field of view.
I am particularly fond of the adjustable 3 click eye cup. It is the first pair of binoculars that I can easily use while wearing glasses.
I highly recommend them.

[Center] Very crisp images and easy to use focus knob. Night and day against my last pair of Discovery. Highly recommend these based on construction and image quality.

[-3 to +3] I wear eyeglasses so I need a binocular with long eye relief. Opticron is one of the few manufacturers that produce 10X42 binoculars with eye relief of 20 mm or more. (I find that I require just about 20 mm of eye relief for comfortable viewing.) I’m very happy with my purchase of the Natura 10X42. Eye relief is adequate. Images are crisp. In low light it produces a slightly brighter image than my 8X42 binocular from another manufacturer. Construction quality appears to be very good and I like the way the rain guard and objective lens covers fit.

[-3 to +3] After comparing for a long time, I bought this 10x from B&H, I satisfy with it, I can see small words 1.4 meters away, the whole field is very clear. All in all, good!

[18 mm] I bought these as a gift and was not there when they arrived with the recipient but I know they were delighted with them. I was very impressed with the delivery information and the speed with which my order was dealt with. They were sent from the USA to Australia and all the paperwork was handled by BHP and obviously as binoculars are delicate objects they must have been extremely well packaged. Well done.

[Center] These bins are a nice compact size, a bit larger than 25mm bins so easy to hold but still much more packable than most 42s. I was torn over which magnification to buy but have no regrets in choosing the 10x. The FOV of these 10x is about the same as many other 8x so I’m finding they’re fine for birding and no issue with jiggling. The eye relief works fine for my eyes with glasses on and the view is certainly bright, sharp, and clear throughout. Overall very pleased.
