I went in to get my right helix pierced and it was probably the best piercing experience I've ever had.
The paperwork took a little longer than I would have liked, but while they were getting everything done Jeremiah showed me the jewelry they had and I picked out something really beautiful. The price of the piercing, jewelry, and aftercare spray was about $45, which is very reasonable. They have coupons on their Facebook page, which I forgot to print out so I missed out on a discount, but it was still affordable. When Jeremiah took me back to get pierced, he joked a lot and was very laid back which made me feel relaxed.
The only thing I didn't like was when I asked him what to do to protect it while sleeping (since I move in my sleep a lot) he just said, "Don't sleep on it." When I asked, "What if I do?" and all he said was, "You won't." Not the best advice in the world.
But their jewelry selection is incredible and I am in love with my piercing. I'm thinking about getting my left helix done in the Spring and I know if I do I'm definitely going to Halo.
