Has anybody had their magnetic closure break on them? I have a Sophia and rarely use it. The one time I bring it with me on a trip, the magnetic closure part broke. One side of it completly came off. Luckily, it was stuck to the other magnetic part. I was able to stick the prongs back in the hole however, it came off again and I had to search for 20 minutes on the street looking for this magnetic part! Went directly to the MJ store and they said they will fix it but since I didn't live in the area, will have to make a trip to my local MJ store. They better not charge. But wondering if anybody has had any experience with this issue?
