Very pleased with Treatlife dual dimmer/timer. Easy to install and program. However, more than a year later, one of the outlets stopped working. Through 鶹, I found a contact email address for customer service. I eas very surprised to received an answer the very next day to help troubleshoot the issue. When nothing fixed the problem, the shipped me a new unit free of charge that I received within a week. Everything is working great again. Tremendous customer service, highly recommend.
