[This review was collected as part of a promotion.] I think the sonic care 4300 is a great toothbrush. It cleans my teeth very well. I have used Sonic toothbrushs for years now and had to pick another model do to my older model be discontinued. I am very happy with my newer model and it's performance so far, about 1 month. I would recommend and have recommend the Sonic toothbrush brand to my family and friends.

I bought this toothbrush to replace another Phillips Sonic Care toothbrush I had. This toothbrush is far inferior to the one I had. It barely moves at all and even the slightest pressure makes it stop working. I understand it goes off to prevent too much pressure on the teeth and gums, but even the slightest pressure and it stops. It’s super loud. Really hate it, but not sure I can return it. Deep sigh.

Only giving this 4 stars because this is the second set we've had to buy. After a couple of years the head unit gets really loose and noisy and entire toothbrush needs to be replaced. This happen twice. The first was inside the 2 year warranty and they replaced it for free. The second broke just after the warranty expired. There really are only 2 choices for electric toothbrushes, Phillips and Oral-B. We stayed with Philips. We hope these last longer.

I don’t like it. I have an Oral B and wanted to try the Sonic— to compare. I felt like all it did was vibrate, but did not clean my teeth nor remove food particles between teeth. Very disappointed!

Clean teeth, This is my thrid set of sonic care tooth brushes, when I went to the denist he asked me how many times a week I flossed and I told him I didn't. My teeth wear so clean he couldn't believe it. Just from brushing with the sonic care.

The look and feel of it is sleek and comfortable. This is my first Philips Sonic toothbrush and so far I am pleased. Battery lasts a long time. The toothbrush case is light and compact. Perfect for travel.

Not sure why but we have had to replace ours in less than a year.

Great price, but brush heads are useless. Once you buy decent heads, price about retail. No big deal.

It was so loud. It sounded like a swarm of bees. Also the brush heads were the size of a child's toothbrush. Hated it.

Have to wonder if these were factory seconds? The manual in the box was not the correct manual for the brushes?
