We will never know. They were refurbished.
However my m2v4 just showed up and they are bstock so should be brand new. Will be interesting to see if there is any break in noticeable.
It will be awhile before I can try them as my yammie is doing double duty at work while I’m still waiting on the za1000 I ordered. Ordered April 30 and still waiting. Hop fully my yammie doesn’t get broken there. Yikes.
How long did your M3s take Kodiak?
