This article applies to Mighty Hoop 15" x 13" Melco Part Number 35872.
The 15”w x 13”h is unique in that there is only one correct orientation between the bottom and top hoop rings. If not aligned correctly, the magnets will not hold firmly. If the magnets are not holding firmly, check the alignment between the hoops with the photo below.
The magnets have positive and negative fields and the bottom ring must be aligned as shown in the attached picture. If the ring is upside down or oriented in the opposite way, it could detach. When aligned properly, the strong points of the magnets come into contact with each other; when mis-aligned the contact is weak.
If the HoopMaster Adjustable Fixture is used and the thumb tab on the bottom ring of the hoop is positioned toward the top of the shirt, the top ring will need to be aligned so that it matches up like the picture above.
