I have had this nose stud in for almost two years. The ball end is big and it is a little difficult to get in and out, but I do not change mine regularly so it works for me. Once it's in, it's fine. I've had absolutely no problems with it. I used to use the nose screws but found they were hard to get in and came out easily when I wiped my face with a towel and my daughter and sister kept telling me I had a "booger" in my nose as the wire on the inside was very visible. I wonder how many times people looked at me thinking I had a booger and I felt embarassed. I have tried several nose screws and studs and by far I think this one is the best.
