I had gotten my ears pierced in 6th grade and after many years with a earring hole that was a bit lower than the other, and prevented me from wearing certain earrings, I headed to Sadu to see if anything could be done.
Now I had hated my first two experiences with piercing, so I wasn't too stoked to have to get another one.
I couldn't tell you if I made an appointment or walked right in, but I was one of the only people there and I was waited on promptly. They assessed the situation, agreed that the piercing sucked and told me my options.
All I cared about was that they could fix it! Fast forward 15 painless minutes, I had a new aligned, centered, amazing ear piercing. It was so pain-free that I even considered getting more things pierced.
You can tell that they definitely want to get the job right and are serious about their piercings, even just simple ear piercings.
