have used for months. appreciate the small head because I have what my dental hygenist diplomatically calls a strong gag reflex

I and the rest of my family have been using Kyoui Sonic brushes since 2015. We have always received excellent customer service when ordering new handles and brushes. Replacement handles were also promptly delivered. I have told my dentist's office about how great Kyoui Sonic brushes and handles are.

At first I wasn’t sure of the flavor but I’ve grown to love this toothpaste! My teeth feel so clean and I think whiter after brushing and my mouth is fresh. I recommend this toothpaste!

Terrific!!! Better than Sonicare. Angle is better than straight.

Waited too long to replace, what a difference these make!

We have been using the toothbrushes for 3 years now and have not gotten any cavities since then, kids included!!! Amazing.

I love this tooth brush! I tested with my own EMF reader to verify as well. I love the curved head! Seems so much easier to reach my back teeth. This toothbrush feels so so good on my gums and teeth. Very satisfied!

I've been using a Kouri / Curvy for over 5 years. Early on, b/f we knew better, I had several titanium implants which eventually all had to come out due to reactivity. Due to bone loss, I now need a partial denture. The Curvy is able to reach into those interior sides of exposed teeth as well as being most efficient at the typical exterior and interior surfaces. I very much like that it does not have a scrubbing action, and that the vibration rate is so high. When you have had dental issues, you more than ever want to preserve what you have left. I feel the Curvy/Kouri is the best option for me. I also like that they will send you new heads b/c I would tend to use one too long. The pointed attachment is great, too. No complaints. Only praise for this brush. I use it on my flipper, too.

This is my 3rd or 4th brush handle. This was confusing: are you changing your name? And why fix what is not broken? I will give away the 2 bonus brushes I don't need, but thank God I kept my old carrying case. Why replace it with brushes I didn't order? And I know that the new base is sleeker, but I liked having a spot for the second head between uses.
