The electric toothbrush I was using before was the cheapest Oral-B you can get. I used it on and off for almost half a year, but I always felt the vibration just wasn’t satisfying enough. I even figured that’s probably just how electric toothbrushes are. Then the thing broke a while back, so I started thinking about buying a good one. Originally I wanted the Philips DiamondClean HX9352 — it had dropped to around 900 RMB on Amazon UK at one point, and JD had a promo recently where you got one free with furniture, so you could pick one up on Xianyu for around 800. But when I posted on WeChat Moments that I was going to buy this toothbrush, my ex (sort of, I guess?) said she wanted one too. So I figured I’d just give her the DiamondClean and, since I couldn’t afford a good one for myself anymore, settle for the second-tier HX6711.
