I have a friend that has the 10x Razor binoculars. I have used them and was able to compare them to some others.

They are good quality binoculars that are imported from Japan and rebranded with the importer's name (Vortex). I think you will be happy with them and the warranty should be good for as long as the importer stays in business.

The pair that I used compared fairly well with other models in their price range.
