Just to add to the discussion, KS backers have an extended warranty on the ring. Actual failures being exchanged is a good thing and analysis of the failures helps John and the guys build a better ring!
The section from the returns page concerning kickstarter backers most is here:
"A ring supplied by McLear Ltd has developed a fault within a 12 month period and there are no signs of foul play. Kickstarter backers will get a 2 year warranty, however we can only provide one "like for like" replacement, provided we have one in stock. Any ‘like for like’ replacements that we do not have in stock will be from our available range from our store."
