Bought and installed. There is no free installation in our city, since there is no representative office and therefore there is no warranty repair (Hong Kong), and through the point of sale it will be long. Water began to ooze immediately from the inside, in the region of the 2nd cartridge. A few drops per minute, but it's enough to fill everything under the sink overnight. I opened the block with connections and found a leak from the "quick connector" connection (there are a lot of them, a fee for compactness), it spontaneously "slipped" under pressure (poor quality of the quick connector). Also, after inspecting all connections, I found that one connecting tube was cut lengthwise during assembly and also leaked. Total. *I do not recommend this model. Due to poor-quality connections, there may be a leak and damage to expensive furniture. There is clearly no quality control and leak testing at the assembly.
To supplement my review, I have attached some photos that show the highlights of my experience.
