Great Product - Fast & Easy Well you would not think that a toothbrush could be reinvented to the point where you would say it is groundbreaking. But . . . the Feno is just that! Very simple to use and the it makes thorough brushing fast and easy. The brush has a simple interface without complicated 'guidance' on how to brush and where to focus. In less than a minute your teeth are very clean. Simple, smart and great results. It deserves even more than 5 stars! Also, the foam is very easy to use and effective and compliments the simplicity of the device.

Listennnn. Even as a person with “buttons” while doing Invisalign this toothbrush is quite the arsenal in keep my teeth clean when I have to frequently pop aligners in and out. I can’t imagine how much time I’m saving! Additionally, my teeth are actually clean. Like — really clean. Cannot recommend enough.

Great toothbrush, brushes all my teeth on both sides all at once and my teeth feel better cleaned. The vibration seems to remove more plaque - my teeth feel more smooth. I also don't brush my gums too hard anymore with my new Feno.

Customer Service is outstanding. The team is VERY responsive. Recommendations for improvement: 1. packaging of foam is unnecessarily difficult to open, 2. lack of included container for mouthpiece is unfortunate (and I heard they have them, but they're not able to be purchased because they're on backorder), 3. app interface isn't as user-friendly as it could be, 4. camera utility is technologically-limited (pictures are consistently "too dark" no matter the ambient lighting.)

Customer service has been amazing. It is sometimes too strong so I just turn it down but I love knowing it takes only 30 seconds and my teeth are getting cleaner than by hand!

My Feno has really helped my routine. I've been able to brush more efficiently (and effectively) in a shorter time! Worth the wait! Also, their entire customer service support team has been wonderful. Any issues have been promptly addressed.

I love the way it cleans my teeth in 30 seconds. It feels super clean and gets my gums too. To me it was worth the price!
