I recommend this toof brush to so many people! After receiving one as a gift, I signed up for the auto renewal because there’s no way I could go back to regular brushes. My boyfriend and I get the couples pack and after gifting them to his parents, they signed up for the same as well. It’s great for sensitive mouths but does such a great job cleaning. I recommend these to friends and family any chance I get. Great customer service, timely delivery and much better to support from a small business. They make it easy with these awesome brushes.
