Review title is Great for Travel. [SEP] Great for travel and doesn't eat up the batteries too quickly. It cleans just like my plug-in Elite model and uses the same brush heads. My only complaints are that it doesn't have the 30-second alert beeper to tell you when to switch sides and it doesn't fit in my Sonicare Elite case. I haven't found a reasonably priced case for it yet. But overall I'm happy.
