you should search up some of my old threads - I had 4 Leica CRFs go belly up. just stopped working. They'll replace them for the warranty period (2 years ?) then you have to buy another.
they do not repair or refurbish them. they'll give you a $100 rebate on a new one.

that said, when it works, it's light years better than the Leupy.

Personally, I bought a Swaro. The latest model is quite fast and appallingly accurate/repeatable. pricey though.
