Shell ordered to replace that of Peugeot origin whose buttons were ripped off. Free shipping is a little long but knowing that it comes from China, it is normal; we can not claim to an express delivery from across the world for a piece of plastic to less than 2! Once received, I removed the old and after observation, I have replaced the half-shell comprising the buttons. It adapts perfectly on the half shell that has the brand logo. I passed the tests: the buttons respond well as originally. So I did nothing wrong, and I suggest this alternative model.
