I have several on high recoil rifles and have never had a problem with durability or performance. They hold zero in all types of climate change. I am a part time gunsmith and have had no issues with mine in the 20 plus years I have used them. The binoculars are just as clear as the scope.
Pros: Quality, durability, value and clarity.
