TRUST Equestrian stands behind the quality of the products and warrants them against all defects in material and workmanship. However, we offer no guarantees in the event of biting on the Inno Sense mouthpieces. The bit should rest on top of the layers, this is the part of the jawline without teeth or molars. If the bit is correctly placed in the mouth, the bit does not touch the teeth or molars. There are horses that due to a dental problem, damage the bit by biting it or lift the bit upwards with their tongue, so that the horse can reach the bit and thereby create the possibility that the flexible material of the TRUST Inno Sense flexi bit gets damaged. The material of the Inno Sense flexi bits is FDA approved, which means it is non-toxic and does not contain plasticisers. Defective TRUST Inno Sense flexi bits with bite marks shall therefore not be reimbursed by TRUST Equestrian.
