Yes I have also heard that the danger is not that the sequins will fall off but that they will shread some clothes. Leopard scarves for example must be kept a safe distance from these bags at all times.
The sequins are really sewn on very very tight and and it is very secure. I just bought a black Eclipse Alma and I was astounded at how fabulous the detailing on this bag truly is. My SA did say to not have the bag rub against silky fabric.
I agree that the danger with these bags is the damage they could do to delicate clothing rubbing against them (fine cashmere, leather, silk, etc.) not the sequins falling off. The sequins are attached really well. I did not think I was going to like the bags because I do not like a lot of bag bling but these are very beautiful bags esp. the lovely leather accents- sumptuous!
