The dentist has ALWAYS told me I brush too hard and is the main cause of my receding gums. But since my wife gave me Quip for Christmas (2019) I no longer am pressing too hard or brushing wrong. I’m taking my time and letting the brush do the work. I’ve tried other "electric" toothbrushes in the past but they have been worse on my gums than using a manual toothbrush. Quip by far is the best...and my teeth and gums actually feel better.
Bottom Line: Yes, I would recommend this to a friend
