Good product, weakness in plastic coupling system of two components which, as the case may occur, I am 2nd in 1 year. Also told intelligent monitoring system of cartridge wear is especially smart, to increase the frequency of cartridge purchases! Indeed, it turns red after either the 1200 or 3 months. But three months in all cases, even if you have filtered 300 liters. BRITA should announce a lifespan of 3 months, clearly and not merely to show 1200 l. But commercially it better Brita - L12502- Set of 2 cartridges for faucet filter on white or chrome On Tap - 1200 liters of filtered water or 6 months of use
