CHIIZ – Sonic-powered Automatic Toothbrush

CHIIZ is a new toothbrush project that is currently funding on Kickstarter. It is a sonic-powered electric toothbrush that allows you to brush your teeth in just 30s. In this article, we will have a deeper look into this smart toothbrush, and ultimately, to give you an idea of whether is this CHIIZ toothbrush really worth-a-buy.

Sonic-powered devices are creating quite a buzz these days. Not long ago, there was a Sonic Soak on Indiegogo that has been funded over $2 million and it’s way crazy.

Does it really work?

For sure it does. But we don’t really think it’s as effective as claimed, at least from the negative reviews I read from this one highly similar device I found on Amazon.

And now, these smart people are even using it in the toothbrush space. With that being said, let’s move on to the section below.

Review and Discussion – Is CHIIZ toothbrush really worth it?

First and the foremost, the idea itself is certainly great only if you never heard of it before. What I mean by that is the CHIIZ toothbrush seems just to be another wheel-reinventing Kickstarter product which had been pointed out by backers:

Right after the Amabrush hit a huge $3 million pledge on Kickstarter last year in August, many copy-cats like this one are trying to make a quick buck out of the market. Similar to CHIIZ, as you can tell from the similar appearance, the only changes is the motor and battery part which have been moved to the inside of the mouthpiece system.

On the other hand, some have concerned about this toothbrush really able to fit into the mouth perfectly. As each of us is quite different in the shape and size, not to mention that many of us are having uneven teeth alignment, getting a one-size-fits-all mouthpiece is not really a good idea and can be painful sometimes.

In compared to the existing sonic toothbrush like this one which makes sense to have fine bristles to get to the hard-to-reach corner, CHIIZ’s thick bristles are not meant for brushing into the nook and cranny. It merely uses the sonic agitation for the job which isn’t as effective.

That said, many sonic toothbrushes on the market often use the sonic agitation as a secondary in parallel to the mechanical brushing. The reason for that is to clean off the stubborn plague which can hardly be removed from just agitation.

For charging, each full charge lasts for about 10 days so you’ll probably have to recharge it at least 3 times per month. And each full charge takes 2.5 hours (150 min).

Also, you will need to frequently buy the toothpaste replacement from them. Each 50ml bottle costs you for about $8 to $10, and if brushing twice a day from just you alone, the bottle will be finished in lesser than a couple of weeks. So, it’s a fairly expensive long-term investment. On one hand, you will have to replace the bristle mouthpiece for $14 (purchase via their website) every 3 months. Alternatively, if you would like to use your normal toothpaste, you’ll need a bubbler to create foams which otherwise the toothpaste will not dissolve well (as CHIIZ only agitate but not really mechanically brushing your teeth).

Interestingly, one backer has asked…

It’s actually a reasonable concern as it can cause heavy metal poisoning when leakage. There is always a risk in it.


In overall, is it worth it? No, we don’t think so. As the $90 price (+$20 for shipping) and risk following it are far from the value you get from this system, I would still preferably sticking to my old conventional toothbrush for the moment. Anyway, you will be the judge, if you would like to give this CHIIZ toothbrush a try, hit the green link below to get your Early Bird while it’s still available!

Alternatively, why not try this awesome sonic toothbrush by Philips instead? If I were you, I will not even have a second thought about it.
