I took the turbine cartridge from them, and it lived for exactly 2 days. I started whistling right away. I thought maybe the nozzle had burst, no, not the nozzle, the cartridge. Although I did everything according to the instructions - I washed everything, the oil is new. In a telephone conversation, they didn't let me say a word, they interrupted, they referred to "you have something with the car," we have never had any spare parts for all the time of marriage. And they said about the warranty conditions, "we just ripped it off the manufacturer's factory," which is their literal answer. I didn't get on their nerves. I installed the turbine from disassembly, it has already been 30 thousand. The desire to contact them and recommend them was completely discouraged.
