I don't know who makes the ez red ratchet (I'll guess Kabo)... [but I'll say this] I have a harbor freight extendable ratchet. My co worker bought an EZ Red one from Mac. Aside from EZ being a flex head, the ratchets felt identical.
Even if they aren't from the same manufacturer, they may as well be identical. Meaning, I don't see how its worth paying EZ Red's price for a HF tool.
I say grab the GW 120xp 4piece set and a HF extendable ratchet.
