I had gotten acrylic before, and my ears had a terrible reaction to them. So I got these and it has been great! A few issues I have had is that it arrived with one band broken on one of the tapers, kinda bites, but I can use a band from one of the plugs when I need to. Also I noticed that some of the bands when in the smaller range, especially the 12, the bands are super hard to get on to the plug when it is in, much less out. I struggled for a good 30 minutes to get the band on. Once they are on they are on, and easy to take off when you want them off. But as I get higher in size the bands are getting easier to put on, so it was a small phase for me.
