I've found Quip to live up to its advertisements. Great product, easy to use, and definitely much less clunky than other electric toothbrushes. There's absolutely nothing that I dislike about Quip.
While it certainly feels like Quip is doing a great cleaning job on my teeth, I guess "the proof will be in the pudding" when I visit my dentist, next week, for a regularly-scheduled checkup.
Bottom Line: Yes, I would recommend this to a friend
