I own a pair of 10x42 Leica's and a Leica Spotting Scope. I jumped through the hoops with the Warranty department with them. I thought I was going to have a coronary over getting the Binos warrantied as I had lost the receipt. They were bound and determined NOT to cover the binos unless I could produce the receipt. I argued with the place I purcased them through till I was blue in the face that I needed a receipt. I finally wound up going online and paying $2 for a credit card statement and had it sent to me and showed the store the exact date of purchase and they were then able to go back and pull the receipt and let me drive down to the store and make a copy. Then and only then was Leica going to put my Binos under Warranty. I decided that day that was the last Leica product I was ever going to buy. NO MATTER HOW WONDERFUL they are. And they are Wonderful!
