Satisfied with the purchase. The price, of course, is not low, but in comparison with osmosis, in principle, it is not at all high. The filter really works and saves you a lot of worries, it's not a pity to pay for it. Pros: Outwardly, you can’t tell, but the taste of water has changed a lot, it has become softer and more pleasant. I have always been afraid of tap water and, apparently, for good reason. It's scary to imagine what I drank before I bought this filter! Water now, according to the instructions, is purified not only from harmful impurities and metals, but even from viruses and bacteria. 5 liters of tank is enough, never had to wait for a set. My installation was free. The whole system fits under the sink, nothing gets in the way. The kitchen even looks different with the new faucet – very stylish. To change modules, there is a special system of when and what needs to be changed. The most frequent are K2 and K5, once every 3-4 months. You can buy in advance and easily change when the time comes. With its cons: The filter sometimes makes sounds, murmurs, I had to get used to it.
