Disappointed
While I like the actual toothbrush, it’s impossible to get brush heads in stock. The heads are no longer available in the app where I can use my smile points. When directed to the website to purchase (without points), you can’t buy them because they aren’t in stock. I’ve been chasing brush heads for over 6 months. The irony is that the smile question today was “how often should you replace your toothbrush?” While the Colgate app agrees it’s 3 months, it’s not easy to do with this product.
