DiamondClean Smart 9700 Rechargeable Toothbrush (HX9957)

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

Bought the highest end sonicare set three times. One of the two always developed really loud buzzing sounds. Theoretically it could be fixed, but I opted to return and replace. After using sonicare for 15 years, what back to oral b. Design isn’t as slick, but works great and was way cheaper. We’ll see what my dentist says in six months.

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.

Sonicare diamond clean user here. Going strong 4th year. Before the black redesign i had the white one. It worked great no issues but the power button seal broke and I started getting water in so I replaced it.

I am not a fan of the vibrations of the SonicCare. Much prefer the oral-b heads and how it functions. I also like that after the 2 minute time it keeps going so I can get my tongue. I don't think either one is really better. Do it based on replacement head cost.

My newer one is a diamond clean and is going very strong. I have no idea what the other one is, it’s a million years old

I have no idea. I bought it like 3 years ago by now
