Very impressed The binoculars arrived quickly and well packaged. I bought them to replace a 10" telescope that was getting too heavy for me. Although they will never perform like a telescope I am very impressed. Good light capture and crisp images of the moon and orion nebula. They do need a tripod.

For me, faultless I was using some Celestron 15x80, which I was happy with. These are a big step up, and I can't see me wanting anything else, save a telescope. They look, and feel, well made, but not overly heavy. I've got them mounted on a p-mount, but also use them on nocturnal dog walks, on a monopod. (14/12/2020) Kepler - Llandysul
