Never buying another Sonicare
I have been a longtime customer of Sonicare since I was in the dental field 25-years ago. I will never buy another Sonicare product. Bought this product in January 2021. It hasn’t lasted 2 years and I’m on my second one. After the first one just stopped working after less than 1-year, I reached out to customer service. I was provided with a second one and was told the warranty will only be based on the first purchase. Now, 6 months later the second one suddenly stopped working. It would be more cost effective to purchase the $29 generic version sold on Amazon. Even if you buy one annually, you would still save money based on the $200 price tag. My kids have used this generic version and it is still working 2-years later. Don’t buy unless you like throwing your money away. Customer service is a real hassle and I had to jump through hoops for the first replacement.
Thank you for your feedback
