It is sometimes amazing how much frustration and time can be saved when you have the right tool for the job. We found these especially useful for connecting and disconnecting ball links on V-tail slope gliders. You may find these useful as well for your own, "can't quite do it with needle nose" ball links.
The pliers aren't the greatest quality but they do the job just fine. I bent one of the lower jaws on my pair (squeezed too hard when I was not lined up on the ball properly); bent it back straight and they still work fine.
Definitely worth the four bucks.
