Paul Parrino purchased from Daves Professional Wheelchair Service a wheelchair manufactured by 21st Century Scientific, Inc. The sales brochure from 21st Century Scientific stated that the wheelchair would serve [the buyer] very very well for many years to come. Parrino had problems with the wheelchair within a few years and filed suit against Daves and 21st Century for breach of express warranty. Both defended on the grounds that the statement on years of service was puffery, not an express warranty. Are they right? Explain
