Good Brush.
Honestly I didn’t think this brush wasn’t gonna change my brushing habits but it did. The app is very cool, it tells you when it’s time to change the brush, and it shows you how well are you brushing, you can also collect points to buy toothpaste and brush heads.

Love This Thing!
EDIT: I will say that the price hike is crazy. I bought this for $12 on May 4th 2024 and now, as of Nov 7, 2025 it is $50. i’m all for great toothbrushes but don’t really like to support companies that price gouge especially in this economy Amazing buy!! Comes with access to the app and if you brush twice a day, by the end of the year you should have enough points to get a free toothbrush. Tells you what spots you missed too! Had it for almost a year now and still working well.

Still Going Strong
Bought this at the beginning of 2022 for 19.99, still going strong. I must say the price difference is actually crazy because in 2025 it’s $50!!!??? Still use it now pretty great brush. Only thing is over time the handle got pretty dingy despite me keeping it clean. Works well and no complaints. Have used the app in a while, but it worked well when I did and I get free brush heads.

App with these is great!
If you sync these to the app not only can you keep track of brushing and stats, but you can also earn rewards for free dental health items! That was such a plus for me. I got these for my kids and it allowed me to keep track of how well they were brushing but also gave them fun incentives!

My favorite toothbrush yet!
This toothbrush came with a nice little travel case and a set of batteries. At first I worried about the small size of the brush head but it actually is perfect. The toothbrush also had different modes that adjust the vibration power for teeth that might be a bit more sensitive. The app was super easy to set up and allows you to collect “smile” points every time you brush that you can use towards future Colgate products (toothpaste, toothbrushes, etc). Compared to other electric toothbrushes I thought this was a great price and I would recommend to others!

Was great for a few months then shorted out and died
I really loved this toothbrush while it lasted. The accompanying app is a bit clunky and annoying, but I liked earning points when I brushed which I could redeem for products and I noticed an improvement in my oral hygiene, which is the most important thing. I was forgetting to brush some areas before, so I think the guided brushing was actually useful. But, I guess some water got inside the battery chamber because now, even with fresh batteries, it won’t run, it just gets hot. I tried to reach customer service, but so far no luck. I’d hate to buy a whole new one… but I may have to and worry the same issue will just happen again. Lasted about 6 months.

I bought this toothbrush, and after getting it, it told me I needed to download the app, after downloading the app, and trying to sign up, it said "Country not supported", I am from Australia, where Colgate is from/in, and I cannot make an account, therefore I cannot get my toothbrush to work, and I tried contacting colgate support, after spending 10 minutes explaining my situation, I got the message "access denied" and it deleted my entire message on the colgate contact support website, I cannot get a refund

Hasta el momento me parece muy buena compra. Sin embargo, la app no está disponible en México, así que no se puede aprovechar al 100% el producto

Me encantó el funcionamiento su facilidad para vincular con la app Colgate (Mexico) y el escaneo que hace de la dentadura. La mejor compra que he hecho para él higiene bucal

Para el rango de precio, mejor comprar un oralb, este cepillo no limpia solo hace ruido y además llegó defectuoso
