Out of my Handmade range so a little more pricely 
The Response encourages a horse to move towards the bit but because of the structure of the flat lozenge and the positioning of the joints it discourages the Horse from getting too strong or set on the mouthpiece. As the reins are used together the whole mouthpiece is pulled around the tongue and lower jaw with a really comfortable no pinch wrap effect , the mouthpiece has a structured feel in the centre of the tongue to dissuade the horse from leaning on the bit. The Lozenge is small neat and stays in the centre of the tongue and does not interfere with the edge of the tongue or the bars of the mouth This is a flat lozenge and not a plate a plate would have to be flat on both sides
Very useful for Horses or Ponies that need to
 
·        Pay more heed to the mouthpiece
 
·        That need to be a little higher and Lighter in the frame 
 
·        That need to move forwards  
 
​Loose Ring Cheek 
means that the mouthpiece has a delayed action before it is activated. The rider picks up the rein pressure the rein rolls on the ring a little then the ring rolls on the mouthpiece a little and then the signal gets to the Horse some Horses and or riders hands will respond well to this. The plus points for the Horse are if a particular Horse is a little tentative about applied rein pressure or it’s a Horse that does not like its tongue to feel trapped behind the mouthpiece then the delayed action of the loose ring is a benefit.
