I've been thinking about picking up a PK ring for a while now but I'm worried about the affect it will have on mobile phones, credit cards and over devices such as tablets.
Anyone who wears or uses a PK ring often, can you share some of your experience on whether it's safe to have around digital devices (or even some optical devices, like watches)?
