destroyed in the Seidel-contour brush and battery - it must be adjusted if necessary

in the form delivered by Seidel destroyed the battery in the Rowenta dentasonic themselves (being phased out) and damaged the unit. the insulation extends too far down and needs to be shortened for proper operation prior to the first charge on the length of the battery that must remain clear about 1.8 instead of just 0.8cm (as Blackfort apparently - see picture - makes from home) , Seidel was the battery never tested for this brush, my notes remained unanswered. because although an identical replacement battery has been sent, but I only realized this relationship after this also started leaking, I now have two defective batteries for the price of one. this could all be so simple, unfortunately I have to inform us of an earlier review found only when the harm had already occurred. the anxious council of Seidel, I should quickly dispose of my apparently defective toothbrush, it does not really better. obviously you know where the operation of the equipment does not, for to sell the batteries. Rowenta is my fight against the extremely consumer unfriendly disposable Electric Toothbrush monopoly Braun far!
