Was that enough to encourage anyone to an early upgrade?

Happy bird watching,
Hi Arthur,

In my opinion, forever! I'm perfectly happy with my alpha binoculars, which include Swaro, Zeiss, Leica, and Swift products. They're all over 10 yrs. old and stood the test of time. The last "upgrades" that Swarovski and Swift introduced were actually downgrades, e.g., the 8x42 SLC, and last Swift 804ED Audubon, from which I learned a sobering lesson: Achieving the ultimate can hurt business, so always leave flaws to improve upon in the future.
