Very pleased with these binoculars. The image is very sharp and they are a nice weight. I use them with glasses comfortably and I like that you can lock the diopter ring at my setting. They came with a harness/carrying case combo that keeps them handy. I believe they are an excellent choice for my first binoculars for birding at an affordable price.
