Contrary to what you may have heard or been told, the replacement bands are due to a lawsuit that dealt with infringement of use of the original latex bands. Due to a court order, this is all we are allowed to say about it.
Now, nothing changes in the operation of the Eze. The replacement bands attached a little differently, but the whole process is the same. When placeing the replaecement bands on the EZE, the process is the same other than turning the pullback rod so the “hook” or “notch” is faceing downward. Then when pulling the band through the opening, you will have to “pinch” the tubing to help guide the tubing through the hole.
