Item : B0002M50Z6 Customer Reviews Good product by .. N. Jain (NY, NY) Good product. Happy I purchased the toothbrush. Two minor drawbacks, the base does not indicate that battery is low and it takes 3 clicks before it turns off causing the the foaming toothbrush to splatter about. Poor Reliability by .. J. Didier () This sonic toothbrush gave us very poor reliability and service life. It barely made it through the warrantly period. We had problems with the on/off switch not working after using it for a couple of months. Barely 2 years and it stopped working. My hygentist also told me my tartar build up has been much worse since I changed to to the sonic. Our much cheaper Oral-B 3D is still going after 5 years of hard use and cleaned my teeth better. No more sonics for us. Works like a charm by .. K. Murphy () It helps you brush enough and in the right way. Once you get used to the vibration (after a brushing or two), it's very nice. Electronic brush is effective but don't enjoy using it by .. Candice G. Walker () I know electronic toothbrushes do a more effective job than manual brushing but don't love this. It is my 1st so can't compare to others but I would like one not to remind me of a dentist's drill. Also every time I use that I accidentally hit the power button and either change the speed or tune it off completely before I finish the 2 minute session and I've used it at least 30 times. Good price through Amazon. Excellent toothbrush! by .. Robert Washington (Newnan, GA USA) I have been very pleased with this product. This is my second purchase after the rechargeable battery finally died after 5 years. I have owned others promoted by my former dentist that were much more expensive, didn't work nearly as well, and lasted only slightly longer than their warranty. Quality and function are superb and is a great value.
