Colgate Hum Connected Smart Battery Toothbrush Refill Head, Blue, 2 Pack

Easy travel nice compact

Not too hard and good price for replacement heads on subscription

They work I just wish the toothbrush heads werent so small

Could not find these at my local store. Found them to be slightly hard. I looked on the package, mention was made regarding stiffness of the bristle. I love this toothbrush though, especially using it with the app.

Item as described and great quality.

Silly price model, fine product

Hum toothbrushes brush so much faster and more thoroughly than I could ever do with a conventional toothbrush.

My teen daughter is loving this.

These are real replacement heads for the Hum toothbrush. I have the one that runs on battery and it fit mine, so i believe it fits all of Hum brushes.

The replacement brushes are a great deal. Not too expensive. Great purchase
