Now I hate rubber band tricks!
Why it always seemed obvious to me that although I may not know the method I had a rough idea how it was done and all the twisting and moves required just puts me off.
With this you can do a normal band effect then follow up with SLR and give them 2 bands linked together to keep, or you can just do a quick 2 band link.
This changes the whole thing for me as they are left with a magical object at the end.
If you give them away you will need to buy refills, but I've found most people don't actually want to keep them they are just amazed that you left them to take away if they wished proving they are just normal bands but linked.
This is easy to do and you are also taught how to do Crazy Mans Handcuffs to then lead into SLR.
