Has anybody tried these? I just ordered a Silent Mammoth... which is essentially a coat hanger bent all fancy. It arrives in a few days.

Anyway, anybody have any experience with these sorts of things? I went with this one purely because its metal and I don't want to have some ten-use plastic to recycle if this whole thing leads to improvement.

I don't have sleep apnea but I do think my cute button nose could use a little opening. :)
