In addition to another review, I also bought these to come with "another brand" of clamps that use an arm and leg for an extra Calculate tool Two of us could use 1 set at the same time. This look worked out of the box. The problem was that it didn't spread the clamps as much as the OEM spreader and therefore didn't get enough pressure. To fix this, take the spring out and cut off a few extra coils at the ends, reinstall and everything works great.
