I have two 6.5-20X Dead Hold Vipers, a 44 and a 50, one on a Varminter AR in .223 and the other on a Varminter AR in .308. Both of them are great scopes. Not QUITE as good as Zeiss, but as good as Leupold VXIII's and better than Monarchs for sure IMO.
I also have a set of the Viper 15X50 binos, great glass for the cash.
I used the waranty once, was getting some fogging in the binos (took agood spill with them on, could have damaged seals), they were back in under a week (they actually turned them in just over 24 hrs), no questions asked. No fogging either.
