The reins can be attached at various positions to allow for varying degrees of leverage. The amount of movement in the mouthpiece can be altered by moving the stopper above the mouthpiece. The nose piece is padded for the horse's comfort and a nylon curb strap is included.

Care must be taken, as with any mechanical hackamore, that the noseband sits above the nasal bone.

The Happy Tongue is a solid mouthpiece. It is curved and ported to give tongue relief. The Happy Tongue would be a good place to start if your horse is:
- Shaking its head
- Sticking its tongue out
- Sucking its tongue back and as a result, making an intermittent coughing noise
- Trying to put its tongue over the bit
- Going behind the bit to avoid the contact
- Snatching the reins forward and down

The rider will know immediately if this is the correct bit, as a horse with a sensitive tongue will finally begin to work into and accept the contact. Changing the cheekpieces would then allow the rider to adjust the level of control.
