R.I. Gen. Laws § 5-21-8

Any dealer licensed under this chapter to sell second-hand electrical appliances is required to provide the purchaser of the electrical appliance with a three-day warranty of merchantability and fitness for a particular purpose as defined by title 6A. The dealer is not allowed to exclude that warranty by expressions like “as is,” “with all faults,” or other language that, in common understanding, calls the buyer’s attention to the exclusion of warranties.
