Direct quote from ZR website:
"Zen-Ray guarantees your product to be free of defects in materials and workmanship for the lifetime of the product. The warranty is fully transferable. As long as you are the current owner of the above Zen-Ray products, you are covered by our warranty."
This was the same warranty carried by all of the ZEN ED series glass. I would not be too concerned that ZR won't handle any and all warranty issues for the new 7x36 the same way they handle everything.
