My dentist is so proud 😇 ## Most critical reviews (10 lowest-rated) ### 1/5 — Не работает *2026-08-19* Наверное, нужно разорвать себе рот, чтоб все отсканировалось. Приложение бессмысленно! ### 1/5 — The unit cant not connect to the wifi *2026-07-20* So far the set is painful. The unit cant connect to the wifi. Checked all options. Wifi works fine, refreshed, reinstalled…. Once will figute out the issue, mught update the ratings. ### 1/5 — Очень плохой продукт *2026-07-18* Было две зубных щётки. Обе одинаково сломались - проблемы с батареей. ### 1/5 — Wifi doesn’t work *2026-06-12* My house has the highest reach of Wifi in my neighborhood. I have access point to every room and I connect many devices every day with no problems. I’m standing by the router with my toothbrush in my hand and he’s not able to connect to the network and he keeps telling me to retry I’ve done it 100 times, this thing is useless. Also the mouthpiece is so big that it make me gag can’t brush with this in my mouth. ### 1/5 — Broke after 5 brushes *2026-04-14* Cool idea. Overall, cool product poorly executed. Onboarding the user to the product choppy and overall not as pleasant experience. But the kicker of it all is my $300 toothbrush lasted all of 5 brushes and is NOT waterproof. Support doesn’t really help me just keep kind of running me around. I work in technology and product dealing with software that talks to hardware or IOT devices, I do not see how I fix it without sending it back to Feno. ### 1/5 — Wildly inaccurate, and complete garbage! *2026-03-01* This app is terrible. Super inaccurate. Went to the dentist three weeks after using and had none of the issues the app claimed. Creates a false sense of insecurity. ### 1/5 — Looks bad *2026-02-12* My experience was disappointing. The scan process felt unclear, and I’m not fully confident in the accuracy of the results. Not trustworthy ### 1/5 — Horrible experience *2026-02-11* I’m really disappointed with this app ### 1/5 — Unable to use. *2025-12-04, version 3.1.4* Never got my email once I did(or maybe didn’t, no way to tell) my scan. Cancelling my order because this was a waste of time. ### 1/5 — Horrible app *2025-11-28* This app is horrible. I have been trying for ten minutes just to get proper pictures of my mouth so that o can order the actual product. If I can’t get this to work I am canceling the order for sure **Developer response:** Thanks for sharing this, and we’re really sorry for the frustration. Getting the right mouth photos for your order should be quick and easy. We’ve made recent updates that have improved the scan and capture experience, and we’d love to help you get through this without needing to cancel. Please reach out to help@feno.co and we’ll get you sorted quickly. ## Most praised reviews (10 highest-rated) ### 5/5 — I love it *2026-06-21* My teeth feel different than after a normal tooth brushing.
