Huck,
Perhaps the brand Zmanbands suggests is better, but I used something very similar to what is pictured in your link. Very easy to use. You don't even strip the wire (in fact, shouldn't).
The instructions should be on the container: Just pull out the prongs, pull the wire through the white case, pull the prongs apart and insert the wires, squeeze the prongs closed and reinsert into the case. You are done. Takes a few minutes.
