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

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.

I have bought this brand before with a usb c charger on the bottom. Although it looks like they replaced it with a standard adapter. I would not recommend buying this brush. It will eventually short and not charge.

There's a reason major brands rely on wireless charging. Water kills charging ports. Especially when it's mixed with toothpaste.

You sound like you like to overpay and defend companies that don't pay you. Try using the product first and then talk. It's just $6 with 30 day return window.
No, I don't support these ripoff companies who have littered amazon with their sub-par and questionable products. I don't care how much it costs, you're putting this in your mouth...I don't take those kinds of risks. You can, enjoy saving the money, i'm not.

I bought this brand when on sale last year. Use it when i travel instead of my io toothbrush. Works extremely well and you can adjust the intensity. Holds its charge for a long time as well!

I have been using these same kinds of off-brand Sonic toothbrushes for many years and they are phenomenal. I used the brand names in the past but suspect they are all made in the same factory.

Its the bristles/head that matters more. i wish they'd make the base universal to some brand name..

Also confirm code working again. $6 + tax.

Might use it as a travel brush since the Philips One I currently use is pretty weak.

If these heads fit my sonicare, this would be an amazing deal on toothbrush heads. Idk how Phillips gets away with charging like $8/head

How can it be weak? Did you try the hardest intensity and the different level of vibration? I'm asking because I have a few of these and they work excelente, my teeth feel like I just went to the dentist with every use.
Yes, even I tried the highest level of vibration (with 3 dots of LED) and in different modes (including POLISH mode the bottom lowest LED, but usually I use the CLEAN mode the top LED), but my teeth are not clean smoothly.

I hope the seller reading my comments and wishing the manufacture makes the toothbrush head same size w Sonic. W, because it is about 1.25 - 1.5 bigger than Sonic. one. That is my own opinion, and each person has different observations.

Code still working and I see C30 replacement heads are currently $8 for 6, so reasonable replacement head costs if this is the normal price (claims to be discounted right now).

Yeah, but the "real" heads are clinically proven with the FDA. Knock-off heads will erode your gums and enamel. If you are going to use knock off heads, only use them with these weak vibrating handles, in which case you would be better off just sticking with a regular non-power toothbrush.

Any idea why those brand names cost a lot more?
