Only a love company Grohe, an aerator will cost not the world (I paid 1.15, you get the safe cheaper). Do not you think you could a dazulegen? The relatively high-altitude run in conjunction with a slightly deeper sink leads otherwise, even if only recently turning up the faucet to a moderate flood around the whole kitchen sink around. With aerator does not happen. From me, therefore only 4 stars, the enclosed application simply does not match the high spout.
