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

My teeth have never felt cleaner

Works very well and compact enough to travel with.

Will buy more

Not too hard and good price for replacement heads on subscription

Colgate Hum is a very good toothbrush. Makes me want to brush my teeth.

Arrived promptly, just as expected.

These are very soft bristles and 2 months of regular use (2x a day) wears them down. You have to replace them every 2 months

I love these toothbrush heads. They are soft and clean teeth well. They are also much more reasonably priced than another brand (of toothbrush and brush heads) I used to use.
