Love it bought two

Bought two Hums, one for me (dad) and one for my 9 year old son. The app really helps him (and me) cover all parts of my teeth with a score telling us how well we have done. His dental hygiene has improved considerably according to his dentist. The connection to the app does take a upto 30 seconds. The battery life is probably half of my old Sonicare - but that is not a problem, just put it on the charger more frequently. The BIG worry is that all replacement brush heads except for purple are sold out, those some vendors are selling them for over $20 for a pack of two. I don't want to buy the knock-off heads - very cheap by poor quality and not well designed for effectiveness. I might be left with two brushes and no heads soon. Already using purple heads on one black and one teal toothbrush. No comments from Colgate on whether these are being discontinued.

Yes, I recommend this product

Great brush!

Love this new electric toothbrushy Colgate. It leaves my teeth clean both on the visible surface of the enamel and between my teeth. Wonderful brush.
