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

They work I just wish the toothbrush heads werent so small

Aweomse

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

My teen daughter is loving this.

Exactly what I ordered.

Enjoyed using the product and app but it didnt even last a year. Didnt expect something in this price range to be an heirloom but I do expect better durability than ~8-9 months.

We got the toothbrush and was in need of some new replacement brush head. Glad that the replacement head was inexpensive and love that it came in a pack of 2. Good deal!

Not too hard and good price for replacement heads on subscription

product as described. Love my HUM!

I am well satisfied with your product.
