Absolutely fast delivery as usual Amazon. Age Single lever of Lidl held first three months closely, after replacing the cartridge again less than a year - the mixer looked like he was already 20 years in service Expansion was very difficult because the attachment was now rusted. The installation of the Focus mixer from Grohe was incredibly easy. The attached installation instructions are very poor, but absolutely not necessary. I have seen many taps fitted, but as simple never went there. The Grohe mixer impresses with its simple elegance, makes a very sophisticated look and the price convinced all! I am convinced of Grohe.
