Sweet review for your binoculars of choice:

1.0 out of 5 stars STOP!, December 21, 2011
By MD (United States) - See all my reviews
This review is from: Leica 8-12x42 Duovid Binocular (Black) (Electronics)
STOP! Do not buy the Leica DUOVID 8X42 - 12X42 binoculars. An outfitter friend and I each bought a pair of these binoculars at the same time, both binoculars failed in the same manner, and Leica did not stand behind either product.
Focus does not coincide when changing between 8X42 and 12X42.
The mechanism used to change between 8X42 and 12X42 does not operate smoothly, and sometimes sticks and locks up.
The eye cups are loose and do not stay at a desired setting.
Use caution when buying a Leica product. Properly complete the warranty registration and keep your original receipt if you ever expect to request service.
