I have a few questions about this one.
1.) Do angles matter?
2.) Do you have to wear it on your middle finger?
3.) What is the ring made of?
1. There are some angles, but they are fairly easy to manage. You have a lot of room to work with.
2. You can wear the ring on your index, middle, or ring finger. Where you wear it doesn't really matter, what matters is that you don't order a tiny size that doesn't fit your larger fingers.
3. The un-gimmicked ring you can wear around is made of tungsten carbide.
