My shaver is like new now! this was a year or two I had to replace worn heads and failing to find the right reference in supermarket I waited until the gates are deffectueuses and damage my skin: finally I found a few clicks reference on Amazon delivered free on the day indicated on the estimate I will wait no longer next time! Carefully check the reference replacement heads (here HQ9) before ordering rather than rely on the model of the famous razor almost every year. The heads of the model is on the doc, the box if we kept it even on the razor itself in my case 'replace heads with HQ9 only'
