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.

I bought these for my kids, and they're great. We've owned them for 6+ months and have had no issues. Multiple modes to choose from.

Quote from MusicShark :
Any idea why those brand names cost a lot more?
instead you should ask why these are so cheap?

name brands put in the r&d, create the product, ensure it is safe, follows rules & guidelines, gets brand recognition, etc.

these no-name rip off companies just take what others have done and sell theirs at cut rate prices and don't make any money doing so.

I bought this few weeks back on the same deal.... can't beat the $6 electric toothbrush with 4 brush tips!!

does what it needs, its soft on gums and you can reduce or increase the vibrations according to your teeth sensitivity

good regular use buy or good for travel as a backup

I was the first one to comment and it was dead when I tried. I wonder if Amazon has some conditional coupons.

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

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.

I had the same experience. I've used and loved oral b, sonicare, knock off oral b, and knock off sonicare all kinda recently. The off brand stuff can be just as good. However, a price this low is flying too close to the sun. It was much much weaker than my other sonicare knockoff I am currently using (aqua Sonic) and just doesn't seem to get my teeth clean. $6 to $12 is probably the appropriate price, so expect what you pay for. I would guess it is about as good as some of the dirt cheap electric ones (same price range) I've got my kids in the past (I always throw them out eventually because they are more annoying than a plain old manual brush). I think I'll stick with $15+ price range next time I want to see how low I can go and still try for a good brush.
