sonicare xtreme
I am really happy with it. This works just like the Sonicare units with the charging stations, except that you change the batteries.  It uses the e-series heads. It does not have the reduced speed on initial use which may be a problem for first time users of sonicares.  The bottom pulls off to put the batteries in. The edges that you need to hold onto to remove the battery cover are a small making it a bit difficult to remove the cover.<br /><br />The only downside is how fast it goes through batteries. The information on the product does tell you that it will go through the regular batteries quickly.  I was getting only 3 days or so which I thought was little too fast.  Lithium batteries last several weeks when the sonicare is used by one person.<br /><br />I give it 4 stars because of the battery compartment cover and the battery use.  If you are already using a sonicare type toothbrush this is one to consider
