There are reviews about Western music posted here and there!! I got it at a university hospital for medical purposes, not for cleaning purposes. I got it at a cheaper price thanks to the hospital gift, but it's true that it can't be corrected 100% anyway, but it's a problem of misalignment, and I'm sure the size and the area of the spine can't be corrected. I'll get it at a university hospital. My double jaw hurts!!! Rather than feeling this kind of thing, I just need to use a respirator for a day and not be able to breathe and it's painful and not being able to eat... That took some strength. ㅠㅠ Phew. Later, I'll have a second surgery at a double jaw adjustment surgery. It is right to receive it. I'm still stressed and have a problem with my lip, so I don't think it would have been okay even if I had the surgery at a university hospital.
