A product with the Good Housekeeping Seal is different from others. It’s passed a strict review by the Good Housekeeping Research Institute. Products aren’t awarded the Good Housekeeping Seal- they earn it. That’s why it’s reassuring to see the Seal, because you know the product has been thoroughly evaluated by the scientists, engineers and technicians at the Good Housekeeping Research Institute. Many people perceive the Good Housekeeping Seal to be an endorsement, but in fact it symbolizes a two-year warranty. The Seal means that Good Housekeeping will replace or refund defective products within two years of purchase, so you can shop worry-free.
