Our Sonicare brush could no longer charge properly. ZT is no longer walked or the charge held only 2-3x brushing by. Since the error occurred quite different, we thought that both toothbrushes were defective. Far from it - luckily we ordered this replacement travel cable.
And voila: two 3-year-old Sonicare toothbrushes invite back to full and hold for several days. This is just a tip for those who want to throw away their toothbrushes equal if they no longer neat store.
