Unfortunately I have to give all the customers right to have warned in previous reviews this product! The product is really of very poor quality, which I was not previously used by BROWN. After just 4 months, the foil has a large hole, which on the skin really hurts, because this will damage and then burns. Since I had been warned, I have my old shaving head and - lifted film and can improve my shave provisionally until clear whether the damage is covered by warranty. Since my razor was dull and the hair has pulled painful, I unfortunately had to buy this spare part to me. An alternative to this original part there was not, unfortunately, so I had to venture the replacement order - despite clear warnings customers - get involved !!! Was delivered, as well as with customers before, not the original foil in flower shape, but a much coarser shaving foil with hole shape. This has indeed shaved, but not more so thoroughly, as the film that was present during the initial assembly. Scherblatt and knife of Erstausrüstun were of much better quality! The shelf life was much longer! I agree with my predecessors and I recognize that this is a disgrace and an insult that ensures the long term takes revenge and is reflected in the sales figures. At a BRAUN razors I have also tired! Not only because of this incident, but because I've noticed that this shaver - for the same price - already shaved significantly worse than my predecessor! Note: I have seen the product complained directly to brown and get on replacement at our expense, by pointing out that it is a consumption product, in which the guarantee is ruled out!
