I have replaced the same type scope after 16 months use.
There is a major issue with the model.
The adjustment for the turrets is 35 moa each way.
However it does not take much to loose the full circular image in the scope.
After some struggling and adjustment I contacted Deben and sent the scope back to them under warranty. It was a faulty design but at the same time it was not a fault as all that model had the same problem.
They reported back to me that ALL the 10x42 have the same problem.
They refunded the present value of the scope and I paid the extra to get a variable 4.5-14x42.
The variable range do not suffer from the problem and have excellent optics .
I must say that through Uttings and Deben I did have excellent warranty service.
