No 30 second timing
I have used it over 2 weeks on the same batteries but when I came back from vacation, I switched back to the plug in version because I prefer the 30 second timing per quadrant available on the plug in. This toothbrush only times 120 seconds for cleaning the teeth.<br /><br />I would recommend this toothbrush for everyone who does not have access to line voltage.
