My first pair of good binoculars. They compared well to a couple of other brands, but I chose these for the warranty.
The first pair had a flaw, part of the diopter adjustment I think; I contacted Vortex, they sent a return shipping label, and I had my replacement pair in about 10 days. Brian, their customer service rep, was very friendly, and got things taken care of.
It's nice to deal with a company that takes care of its customers, and Vortex certainly does. I'll be replacing a rifle scope pretty soon, looks like I'll be going with a Viper.
Pros: Clarity, Weight, Warranty
