While your quip was designed to last, all quips (that have an active refill plan) are guaranteed for life, just in case something happens. If there's a problem, simply reach out to help@getquip.com and they'll be able to help you troubleshoot. In the case of manufacturing issues, we'll supply you with a new quip upon inspection of your faulty one (reviewed remotely). Brushes not associated with subscriptions are covered for one year after their initial purchase. See full terms.
