All who bought the R400 ratchet and socket sets: The ratchet in my set has chipping chrome on the very end of the handle end. I did not see it until it gave me a very minor cut and I felt it. Put on strong readers and had a close look. Yes, flaking chrome.
I called MechanixGear.com and they sent me a USPS label to return just the ratchet for a replacement.
So, have a close look (or feel) of your new ratchet. Otherwise, love the set; and so far, can't complain one bit about the warranty service.
Just to note; I called VIM Tools directly first. They have a non-negotiable $9.99 fee for any return of any item for any reason including for warranty. That's lovely Customer Care.
