Review title is Great product, but stopped working after 9 months [SEP] It's a really good oral irrigator. However, it stopped working for me after 9 months and it's been a hassle trying to get seller contact info and product warranty info.<br /><br />Update: Change my rating from a 3 to 1. Have ordered this product twice, each time with the same outcome: a device that doesn't function after a couple of months. The company is impossible to get in touch with through Amazon or via their website/email.
