Works Well for What it is Supposed to do.
I chose this over other similar devices because it has a built in clamp to hold the fly and button in place.  Without this feature I don't see how it can work.  I have read other reviews where people have used vice grip pliers or other devices to do the same thing that this item has built into it as standard.  The plastic to me is very strong and works well as long as you don't over tax it.  I highly recommend this item.
