Does anybody use a bit adapter to longe?

There was a recent Q on here and I was amazed that no one suggested it.

It is so much easier! You can change direction without having to stop the horse and "re thread" the line - gives pressure to the bit evenly with no pressure on the poll - simply snaps onto the bit rings and has a ring to attach the longe line in the center - and costs about $10.

I can't be the only one using it...
