I just ordered these "newly released" flip sockets directly from Tekton. My only basis for comparison is an older HF flip socket set, but I am very happy with the new Tekton sockets. They are $40 and I received free shipping and earned a few bucks for next time.
So far I've only used the 21mm, but I can tell you that my HF set was damaging the wheels on my Infiniti, but the Tekton do not rub at all.
