I loved this set it was affordable and it was easy to have them all together. But I found out even with the metal gauges they still tend to smell even if you clean them everyday like I do. Also if you have sensitive ear lobes and sleep on the side of you face like I do then you may cut the backs of your ears a lot and may develop a small indention from the O ring. It might possibly just be my ears but still thought I should let everyone know! (:
