Great, if it still worked! [SEP] I purchased this to replace my top of the line Sonicare toothbrush that finally died after 5 years.  Although this one is battery operated, I expected it to last much longer.  This toothbrush worked just as well as my previous one, making my teeth feel very clean and allowing me to no longer to have periodontal cleanings as my dental health improved so much!  Unfortunately, this toothbrush made it through one round of batteries before it stopped working altogether.  This year, I will be purchasing the top of the line Sonicare toothbrush again.
