Title: Never in stock Review: I purchased the toothbrush from an outside seller, they charged my credit card, told me it was out of stock (not back-ordered), and refunded my credit card. Not a terrible experience at all, but a huge waste of time. Does this product review convey a negative or positive sentiment?
