Fla. Stat. § 484.0513

(1) In addition to any other rights and remedies the purchaser of a prescription hearing aid may have, the purchaser has the right to rescind the transaction if the purchaser for whatever reason consults a licensed physician with specialty board certification in otolaryngology or internal medicine or a licensed family practice physician, subsequent to purchasing a prescription hearing aid, and the physician certifies in writing that the purchaser has a hearing impairment for which a prescription hearing aid will not provide a benefit or that the purchaser has a medical condition which contraindicates the use of a prescription hearing aid.

(2) The purchaser of a prescription hearing aid has the right to rescind as provided in subsection (1) only if the purchaser gives a written notice of the intent to rescind the transaction to the seller at the seller’s place of business by certified mail, return receipt requested, which must be posted within 60 days after the date of delivery of the prescription hearing aid to the purchaser, and the purchaser returns the prescription hearing aid to the seller in the original condition less normal wear and tear.

(3) If the conditions of subsections (1) and (2) are met, the seller must, without request, refund to the purchaser, within 10 days after receipt of the notice to rescind, a full and complete refund of all moneys received, less 5 percent. The purchaser does not incur any additional liability for rescinding the transaction.
