I bought this as a gift for my daughter who is absolutely crazy for anything purple. While this toothbrush is pricey, it is definitely a value for the cost . This toothbrush was recommended by the dentist (and actually sold in their office, just not this color) to assist people with periodontal disease to better manage their gum health. I know she will like the smart modes she can select from for Cindy · walmart.com
