Debbiew,
Thank you for taking the time to write this review. The slow-close action of the hinge can last up to 30,000 to 50,000 repetitions, if properly cleaned and maintained. However, if particles do accumulate within the hinge, it can prevent the slow-close action. If this occurs, we suggest soaking the hinges in soapy water for about 20 minutes. This should break down the particles and allow the hinge to work properly again. If this does not work Bemis Manufacturing offers a one year manufacturing defect warranty that is handled through the location of purchase. Please return your defective seat to the store for immediate warranty exchange. A receipt is not needed. Place your item in a clear plastic bag. The retail store does not have to handle the toilet seat in any way, other than to dispose of it for you. They will simply view the damage and give you a new warranty seat in exchange.
Kindest Regards,
Bemis Customer Service
