Review (1/5): very abrasive - made for a person with a mouth of steel
I wanted an inexpensive sonicare but the brushing is so extreme that it pushed back my lower gum. It went back but this is the most abrasive tooth brush I've encountered. I do not think I have sensitive teeth or gums, but my teeth felt like I was wearing down my gums after a few weeks. I don't recommend this to anyone.
