Great toothbrush
Color: Pale Pink
This replaced a battery operated toothbrush I had. My old toothbrush just made a buzzing noise but never actually vibrated or moved.My teeth feel amazing after brushing and I can feel the vibration actually cleaning my teeth.

So far so good! A lot of bang for your buck.
Color: Black
So far, I LOVE this toothbrush. Lots of replacement heads included. The bristles are soft, and even for someone who has dealt with sensitivity in the past, I have zero pain using this. My teeth feel smooth and look brighter. I've been using it for a few weeks and have not needed to charge it since the initial charge. The 30 second interval timer is a fantastic feature. My one suggestion (not a complaint) for the manufacturer: Move the charging port to the side instead of the bottom, and add a waterproof protective cap for it. I am always careful not to get the port wet, but laying it down to charge isn't my favorite thing. Nevertheless, excellent product!

Great Gift Idea for a Deep Clean Feeling
Color: Pale Pink
I haven’t personally used this toothbrush yet because it was purchased as a birthday gift, but I have used a similar sonic electric toothbrush before and really liked the results. My daughter-in-law loves hers, which is actually what inspired me to buy a similar one for my other daughter. The design looks nice, and these types of toothbrushes usually leave your teeth feeling much cleaner than a regular toothbrush. So far, it seems like a great gift idea and good value for the price
