I have been using my Quip for about a month now and can already see a difference. The 30-second vibrations help me make sure I am focusing enough on brushing each tooth, and brushing everything for an overall 2 minutes. I ordered the toothpaste subscription with my brush and am so happy I did. It is refreshing but also has a great whitening effect. Within 2 weeks I had people tell me my teeth looked whiter! I also love that it comes with a stand/travel cover, and that it can be pressed on to a mirror/flat surface time and time again. 100% recommend!
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
