That "Red Emily" is also known as the "Red Baron".
Before you buy make sure the metal clamps are removable/reversable.
Some of the clamps only have one set of arcs cut into them others have 2.
They are reversable so they can be used on two different sizes bottle necks. I brought back 20 cases of 1/2 liter bottles from gfermany. I have yet to break any bottle while capping.
If you hear of anyone breaking bottles while capping this is the reason for it. They're crimping a larger (diameter) neck with the smaller clamps and crushing the necks of the bottle while crimping (pressing too hard on the handles).
A couple of years ago I posted a couple of pictures of the clamping plates (whatever they are called).
