Magnets are strong but after two months expect the string holding it together to break no matter how careful you are with it. My solution: restring it with 50lb. fishing line. Don't use braided lines as it is to flexible and allows the magnets to bunch up. 50lb. is the right diameter. Tie one knot at each end using two needle nose pliers and burn the end with a flame.
Easy fix....why can't they figure it out ?!?!
