Those are the exact ratchets I use, except I kept the hook on the ratchet and didn't mount them. Just press the red button, let them roll themselves up, and toss them in the tool drawer... well worth the marginal extra cost.

Thanks for the link! I just received 2 sets of these and they are so much more simple than regular ones. The self rolling is a great design!
