Battery sucks and gets rusted,
The battery gets rusted and requires frequent change. The battery does not perform at all. The positive side it is a very useful product for children having oral sensory issues.<br />I agree with one other reviewer on this company's greed. The product works with a custom battery that only the parent company makes and it was designed that way to make more money than standardize on something. Shame on this company.
