water leak within months [SEP] i bought this item months ago i worked so well i could not believe it the bristles were soft it cleaned great it was portable and it did not take up room on the sink i thought it was wonderful and was very happy with ita few days ago it started working intermittantly i replaced the batteries still worked intermittantly i replaced the batteries it made a faint humming sound i knew there was a problem and decided to look up reviews on the internet i saw people were having the same experience and it was due to water leakage ruining the batteriesi will contact the philips co and let them know i really love this toothbrush and hope they will correct the leak situation when they do i would definitely buy a new one
