Achilles heel. The same great feature we all love is powered by a brittle plastic rod that breaks at the hinge after 10 or 15 uses. As you can see my tape measure is in near perfect condition, hardly used. I took it apart, and once you get all that useless broken junk out, it works like a regular self-loading block with no buttons, so it's not just junk when you take it apart and gut it. -Aaron
