Vortex Optics Viper HD Roof Prism Binoculars 10x42

The binoculars I purchased are of really good quality, unfortunately once I received them I realised I should have chosen a lower magnification, my fault ! Amazon have been very understanding and set up a return for me and I will receive a full refund when this is done. In the meantime I have already remade my purchase with amazon for a lower magnification pair and looking forward to receiving those.

Good glass at half the price of the “big names”

I have had these binnoculars now for around two years and I have to say that I find the optical performance very disappointing. They are certainly not crystal clear as they should be for the price. Within a very short time I found that the focus was not working correctly. I took them back to the agent who told me that it was the sleeve surrounding the focus ring which was slipping and that I should try rebonding it . This I did and the problem was solved by myself. I gues that I should return them to the manufacturer for assessment under the lifetime guarantee. I bought them as I had lost my 8 x 40 Nikons. These I have now found and they are so much better.

I bought these binoculars to replace a pair of Nikon Monarch 7, which I had lost and used them to whilst on a two week birding holiday in the Pyrenees. The image clarity was between 10%-20% less on Viper binoculars (in a range of lighting conditions) in comparison to my old Nikons. Often I had to get within 20m or birds in order be sure of a correct identification.
