The Eye cup on my leica 20-60x eyepiece dropped off and was lost. I sent it back to Leica via a dealer believing that it was covered by a lifetime warranty. They quoted me £100 to repair it saying that without a receipt the warranty was not valid. I found the receipt and a copy was sent off. I was then told that because I bought it 6 years ago it still did not come under warranty. I was told the warranty for eyepieces was only for 5 years. News to me !! It seems that Leica are just moving the goal posts to suit themselves. I asked to buy an eyecup as a spare part but they are not available. I think that Leica customer service is extremely poor. When I bought the scooe and eyepiece I was told that this was a premium product and I would never have problems with repairs or servicing. How wrong this is. I refuse to pay out £100 for a piece of plastic tube probably worth around 20p !! So I have asked for my eyepiece to be returned in its present broken condition. another totally unsatisfied customer Leica ! Leica warranty terms are a mine field with periods which may be 3,5, 10, 20,30 years or a lifetime. I will never buy another Leica product !
