Not bad, but not what I was expecting
"This is a review for the 4g black stainless steel tunnel with aqua cz stones in the face. The quality of the steel seems to be fine, but I have a lot of issue getting the threading lined up just right when putting them on. I don't ever have this issue with other, popular brand, trades tunnels. Perhaps my biggest letdown though, you can't really seem the stones on the face of the tunnel very well. I believe this is due to the clear layer of what appears to be acrylic covering the stones, presumably protecting them from falling out. This not only changes the appearance of the tunnels, it also makes me feel that they are of lower quality. I have many tunnels with stones circling their faces and they all do well to keep their stones in place without the need for an extra protective layer. I don't plan to throw them away, but I wouldn't buy them again if they got lost."
