Query: Don't bother!

As others have said before, these are huge. Not only this, but the backs are pretty horribly done.I find myself missing both backs after less than a month. How'd they disappear? They fell off while I was sleeping. More than once I found them on my bed, next to me, but there were two times that they just up and disappeared. This is what you call shoddy workmanship.Don't bother with these things, they're a waste of money.
