I’ve tried mine in a Poponcini and it went well but it didn’t hold up and she’s not one to chew the bit. It’s simply such a soft material that if they are fed a treat coming out of the ring I found it started showing crazy wear and was no longer usable unless wrapped in the latex bit wrap. For the money I won’t buy again.
I recently ordered a Winderen bit which I am very excited to try - they are similar to the Poponcini bits but are a more durable gel material that in theory won’t wear out quickly! They also have the option to change out the cheek piece which makes it very versatile.
