Omg!! I rarely write reviews but just had to for this item. I have used electric toothbrushes for years. Always bought the “ Oral B “ brand. I am not exactly sure why I tried this Philips Sonicare but I am soooo glad that I did. This thing runs circles around the different “other” brand I used in terms of cleanliness. My teeth felt so amazingly good after just the first use. Have used for about 6 weeks now and I am still impressed! My other toothbrushes cost twice as much as this one too. So definitely a value for the money! Highly recommend

This is a great price! Just note that it does move in a slower motion! That is why the price is lower! It works great and is worth the price! Great gift for someone needed a new tooth brush!

Compact, light and works great

[This review was collected as part of a promotion.] I really like this 1100 Sonic electric toothbrush. I used a Sonic way back when they first came out and this newer one is much smaller and lighter and the charge seems to work very well. And it cleans my teeth just fine.
