I purchased the 10 x 28 Diamondback HD after considering Nikon trailblaiser and Leupold Rogue 10 x 25. After side by side coparison the Diamondback were easily the brightest and sharpest image. They come with ocular covers and flip up objective which are very nice. Vortex offers incredible value at this price point. They easily compare to 250.00 dollar binoculars. I have pentax 10 x 50 which are very nice but these will be my go to binoc's. Rugged, crystall clear and extremely well made.
