R829GWRQ still seems to work on the black color. Sometimes going through checkout again can help if Amazon is being stubborn.

Terrible tooth brush. Bought the exact one few weeks ago on deal. If you want to vibrate out your teeth use this.

Im going to try it out.
CalmShoe2276, said it vibrates hard. But it has a lot of really good reviews.
Plus it's for my fifteen year old son who keeps losing his sonic care.... so we'll see?!?

Same as the expensive overpriced IO models. Good brush, stays charged forever with daily use.

For the price it's fine. Not as good as my oral-b 1000, but these cheap ones are less than replacement heads. I have one similar to this and no cavities on my teeth. So I don't see why I need to spend $20 on replacement heads for my 1000 brush, when these cheap e brushes are okay.

Any idea why those brand names cost a lot more?

I don't have this particular brush but I have a sonicare and some other random china brand.

The china brand is meaningfully smaller and has less finished detailing. Buttons don't look as water tight, no wireless charging, plastic brush shaft vs metal, less premium feeling plastic - shiny vs matte - and less cleaning modes.

From my recollection they are about comparable in raw performance though. Both have their times and uses.

This brush has multiple cleaning modes, metal shaft that I see, good charging and powerful. Someone mentioned that it will "vibrate your teeth out" but isn't it supposed to be powerful? 5 cleaning modes, 3 levels of intensity. Waterproof. Most plastics are made in China so I am sure the plastics are the same as the expensive ones. I was not sure this new one would outperform my old electric brush.....but it does. Can't beat 6.00 bucks.

Tried several times removing and re-adding the product + code.

Amazon tells me the code is an invalid 😠

I bought this item, but it is very weak, and $6 not worth to return. Back to Sonicare.
