I have to say I get less than I was with the OEM Metz. I forget exactly what I got but it equaled out to about the same cost as running the Metz. So in the end I was spending about the same to run the IRC because it wore out faster but I like the performance of the IRC better. So cost less but wore faster.I don't remember when I put the last one on or I would let you know when this one wears out what I got.Thi8nking about what my bike has on it now I think I got about 7,000 more or less but not really sure.

I learned all I need to know about life by killing smart people and eating their brains.
