The fitting is ever sealed, outwardly and in the run. This seems to me, is not necessarily standard. The installation was straightforward. It has the same mounting system as the most fitting. No large nut, but two threaded rods that are screwed with nuts from below. The valve from the outside is siginificant. On the inside there are a few burrs, which one sees no longer built into yes. Since you have but also the price in mind have. Only the service is a bit strange. To open one presses the mixer lever backwards. As it happens to us sometimes that you open the faucet accidentally when closing on. We have indeed the fitting itself selected. The aerator can be expanded well. Open and pull out a small Allen screw. From the looks I would describe the valve as sleek, slim design.
