I just wanted to know what brand or type of pk rings is best and strongest. also where can i buy one?
I second this. Mine has been working great!G2 is the best i think and they look really sweet too i've been using mine since it came out.
From what I hear SuperMagnetMan is a great site to purchase one from.
I have Blacks PK Ring. This thing is strong, I wear it everyday and it hasnt come close to breaking. Its got a warranty too so if it breaks cha ching get a replacement.
