Lifetime warranty
It was a nice brush, but it only lasted about 3 months. The seal on mine was faulty and got water on the inside, which caused it to stop working.<br />***Update***<br />I emailed the company's customer service and they were so kind and helpful! They replied in less than 10 minutes and offered to replace it for no charge, and I don't even have to go through the hassle of sending the broken one back! I wasn't sure if I'd be able to get a replacement since I purchased through Amazon, but it wasn't a problem.
