[21 mm] These are great binoculars for me to see the birds at the bird feeders at my home. I had a small pair similar to these that broke when they were accidentally dropped on the floor. These new ones work great. I'm very happy I purchased them.

[21 mm] Very small and light. Very sharp and clear image for such a small diameter lens. Would recommend.

[0.45 lb] Quite compact and sharp. The only downside for me is that there are no covers for the front lenses so I have to put the binos back in leather case every time to prevent dirt. When I need it quick, it takes about 10 seconds to reach the case and take it out and remove the rubber lids on rear eyecups, etc. Still 5 starts tho.

[8x] I now have three of these binoculars. I found a case that attaches to my belt and I carry these binoculars whenever I am on a trip. They are clear, the eyepiece adjustment works really well, and the magnification is really good. I use them for concerts, sporting events and travel.

[Center] great binocular for a vety low price

[0.45 lb] Purchased this binoculars to use at live performances. It is compact, has good magnification, and the instructions to adjust the focus are easy to follow. I was able to see Gil Shaham in close-up at a superb recital.

[Roof] My son loves these; they are easy to use and work great. We've checked out birds, people, and cars.

[2.6 mm] Perfect for keeping in your pocket. Not a toy. Actual bins

[2.6 mm] Wonderful lightweight “opera glasses”. Great magnification with a tight field of view for spying on birds at our feeders.

[21 mm] I was between 10x and 8x on a budget set of binoculars. I had a set of 10x25mm that were in a similar price range, but the smaller magnification had a clearer image because the lower mag is easier to focus with. The compact size makes this easy to take around the city, to games, and on hikes. Great little carrying case and strap. The lenses are high quality. I spent about 45 minutes in the store trying 5 different binoculars, and settled on these for the value--the lenses are so clear and the whole case seems very sturdy compared to others that I tried.
