Review title is 17 months and still going strong [SEP] This is definitely the most inexpensive entry into the Sonicare line.  Well worth the price.<br /><br />Likes:<br />-Uses AA batteries, either disposable or rechargeable.  Works great with Sanyo Eneloop or similar "pre-charged" rechargeable batteries.<br />-Very inexpensive<br />-Uses same technology and brush heads as the far more expensive models.<br /><br />Dislikes:<br />-Lacks some of the features of the higher-end models, such as the little beep that prompts you to move on to a different quadrant of your mouth.<br />-No indication of low battery.  When the batteries are done, they're DONE.  Leaves me running around with a mouthfull of toothpaste while fumbling to replace the batteries.<br /><br />I've had mine for about 17 months with no issues other than periodic brush and battery replacement.  Recently added two more to the household for the kids.
