It is sensitive to flatting from pretty minor road debris. Others have had the same experience with the Minits Lite. I put a pretty good cut in my rear tire- time will tell if such cuts are commonplace. I love the way the tires ride and I love the light weight. I guess I'd say if I rode them to the end of their useful life and found that they didn't flat any more often than my other road tires, I'd consider getting another set, but the flats i have gotten already seem to be more frequent than I am used to.
