DiamondClean Smart (HX9904/71, HX9904/72, HX9904/73, etc.)

I have the same one. Had it since 2017 and still going strong. Love the glass cup and travel case/charger.

I switched from oral B to Phillips sonicare after finding a great deal at Costco. I really prefer it

That’s so wild. I’ve had mine for 4 years and haven’t had any issues whatsoever

It was around Xmas time at Costco. It was this one: Philips Sonicare DiamondClean Smart, model#HX9904. it's [$179 for two sets at Costco](https://www.costco.com/p/-/philips-sonicare-diamondclean-smart-electric-rechargeable-toothbrush-2-pack/4000381005?DM_PersistentCookieCreated=true&langId=-1), so my partner and I each got one. I thought it was a pretty good deal seeing that they are normally $200 each for the full set, including the charging glass and chargeable carrying case. I haven't had any issues, it is sleek and clean, the heads are also always for at costco. I also like that if I charge the travel case ahead of time, I can travel for like 2 weeks without needing to recharge. I also like that the typical charging cord is protected by a glass that the toothbrush actually sits in, meaning it never gets wet or jostled around. Anyway, others might have a different opinion, but I like it a lot compared to the Oral B, and the charger on that oral B stopped working eventually. Also, costco is nice because if something \*did\* eventually happen to it, I could go in an exchange it. But I've had this for quite a few years and it feels brand new.

I've been using Sonicare toothbrushes forever. I usually get the package of 2 of them, in case I can convince my husband to use one (unsuccessful so far) or for travel. I like the one I have now since it has more "intelligence" and lets me know when to replace the brush head.

I had one of the old diamondclean models and it stopped working so i ordered a new diamondclean model from philips which was useless - i ended up buying the older model from aliexpress and it worked perfectly

Diamond care. Nothing comes close.

Have you tried the Diamond care? Compare it to all the other models out there and again, there's nothing that even comes close.

Another Sonicare user here. My teeth are definitely cleaner since I switched from a rotary brush to this. I know it's anecdotal evidence, but I can feel the difference every day.

I'm mostly moving it and not applying a lot of pressure. I think in the user guide it said to use a ~45 degree angle, but I need to check. I have a higher-end Sonicare, but afaik it's the same speed of 62k brush movements/min as the one in the picture. It could be that my rotary brush was shit, but it did have a new brush. I definitely feel that my teeth are better brushed and stay also cleaner longer when I started brushing with Sonicare.

I looked specifically for one with a travel case, but those are usually the higher end (Sonicare 9900 and the like). I tried a cheap one from Concept but it cleaned noticeably worse than my Sonicare. Then last year I snatched a new Sonicare for 50 euros at a clearance sale and I'm very happy with it. This one has a built in USB A cable to charge.
