I’ve used this bit for a little over a week and my horse seems to really like it. Despite being 17.1 hh, he has a tiny mouth (5”), low palate and larger tongue. He loves rubber bits but when they are too thick I feel that they impede my aids. After going through a couple different happy mouths I wanted to try something with softer rubber. This seemed like a perfect option and my horse seems very happy with the switch! He’s not a chewer so I don’t think I can speak to the durability of the rubber. But if you have a horse that loves rubber but has a small mouth and low palate this is definitely a good option.
