These are the best pair of binoculars I have ever owned. They are also the first pair of roof prism binoculars I have ever owned. They are lightweight and relatively small considering the 50mm objective lenses. Excellent clairity and plenty of magnification. I compared them to a pair of Swarovski's of similar size and power and they are not quite as good as the Swarovski. But then again, they are about 1/8th to 1/10th the price. The camo pattern and coating on the binoculars appears to be very durable as they have shown no wear yet. The spin up/spin down eyecups allow you to use the binoculars with or without eyeglasses. They are easy to focus. Excellent light gathering at dawn and dusk. I also purchased the Leupold X-treme straps and like the combination. The only major complaint is the lens caps. They are not very good. They are plastic pieces that snap in to the objectives. The do not attach to the binoculars so you have to put them in your pocket when planning to use the binoculars. I expect that they will get lost eventually. Swarovski's lens caps stay attached to the binoculars. This is a minor thing, but is the only real complaint I have.
