Click clack and ready. Easy to connect and no leaks, etc. for 3000 liters of autonomy and 50% cheaper than others I have tried over time. I put it in an LG refrigerator with a water and ice dispenser. I bought 2 from the beginning due to the price, but I will definitely buy again. The only thing that might seem to me is that the water tastes slightly sweet, but it's normal.
