none of the rated carabiners i received are stamped with any rating details. rated carabiners are supposed to be stamped.
you even show a picture of the stamp on the carabiners on the product page.
other than that, pretty good.
Its strong enough yet supple to flip to next location with ease . one of the better ones ive used with the inner cable for relocating without fighting or binding of the Lanyard at buckle when new .
