I have three brushes, and the Quip, while wonderfully portable, does not satisfy like the Oral B Pro 3000 or the Sonicare Diamond Clean 9300. I use it the same way as I use a manual toothbrush per instructions from the best dentist I ever had, years ago, angling the brush head down towards the gum and sort of flipping it up to remove plaque. That's OK, but the Oral B does that for you; you don't have to manipulate it. I did order Sonicare Diamond Clean 9300 from eBay at a discount, but did lots of research before committing to it. It sounds like a tie with the Oral B pro and far more portable since it comes with a glass for wireless charging, which can be used anywhere in the world.
