Great purchase!!!
You will notice whiter teeth within days, your teeth feel cleaner, gums feel tougher, and battery life is amazing.  It will go up to 2 weeks on one charge.  It has a built-in timer so you know how long to brush each quadrant of your mouth.  It also has 2 speeds for sensitivity.  Great purchase, a must have for anyone that is particular about oral hygiene.
