Mine is new. I ran through 60 rounds of Blazer Brass, with no problems. Got my Crimson Trace zeroed in. Came home and did a nice second cleaning.
The biggest advantage, to me, of the CT, may be using it at home, as a check, while I work on quick aim.

Almost ordered some #1 rated Eezox, but, with the limited sources, decided I may just stick with close #2, Breakfree CLP.
My Hogue Handall Hybrid grip and Remora holster should be here next week.
