Has major flaw

I had an older model Sonicare that lasted years. The newer e9500 seems to last only a few months before the power button seal breaks. This has happened twice. My second unit which was replaced by Philips just developed the same problem as the unit it replaced. Otherwise this would be a very good toothbrush but with this major flaw, I am only giving it two stars. See the photo I uploaded that shows this.

Also, on another note... water gets into the brush head. It builds-up "junk" after awhile. Not pretty.
