Customer Reviews
Smooth purchase, useful features
I ordered the Feno Smartbrush and a pack of Whitening Foam. The website was easy to navigate and placing the order was straightforward. It shipped out the next day and reached me in Chicago in about 6 days, which was fine. Connecting the Smartbrush to the AI Brushing App was simple, and the insights it gives are actually pretty helpful for improving my brushing technique. I had a quick question about the app settings and used their online chat support; they responded quickly and resolved it. The brush feels sturdy, and the foam tastes good. Overall, a good experience and a product that delivers on its promises.
Good product, quick delivery
I bought the Feno Starter Kit. It arrived in about 4 days, which was faster than I expected. The brush works well and the app was easy enough to set up. No issues.
Consistent quality, returning customer
This is my third order from Feno Labs; I got the Family Bundle this time around. I've been using their products for a while now, ever since I first got the Smartbrush. The quality is always consistent, and the shipping is reliable, usually taking a week or so to get to me in Oregon. That's why I keep coming back. The foam refills are a good value with the subscription too.

Share tips, ask questions & help fellow shoppers save more
Hey guys, thinking of getting the Feno Smartbrush. How long does shipping usually take to say, California?
How's the Feno Smartbrush compare to like, an Oral-B iO? Is it really that much better or just hype?
About the TrueFit Mouthpiece, how does the sizing work? Is it one-size-fits-all or do you have to measure your mouth or something weird?
Is Feno Labs even a real company? I mean, an AI smartbrush sounds kinda wild. Wondering if it's legit.
What's the deal with returns? If I buy the Feno Smartbrush and it's not for me, is it a pain to send back?
