Mine are fine. They have a twenty year warranty and you can return them to Bushnell if you have a problem or use Amazon’s 30 day return policy if you don’t like them. When you return just click item not as described and the return shipping is free.
Not everyone will likely be as lucky, and will spend time mailing and waiting for a package. Some folks are not using Amazon to try and return (pump and dump), they are trying to buy a decent binocular. By the way that Bushnell warranty is not even worth the paper it is written on. Bushnell is a shell of it self now, (They used to provide some good glass up to the early 2000s - not anymore) I always tell folks they can do better, much better.
