The main factor affecting the reliability of the mixer is the material of its manufacture. Good plumbing is made from brass. Cheaper mixers are made from silumin or zinc alloys. The last 2 are not only fragile during installation, but also short-lived, since they are very quickly corroded from the inside.
Mixer Material Definition Process
Not wanting to change faucets every couple of months, you need to choose brass models. Since manufacturers often do not write the material for making the body, but only its coating, you can use one trick when buying a mixer.
A small neodymium magnet is needed to determine the material of the mixer.
It does not react to silumin and zinc alloys, but is attracted to brass, although not as clearly as to steel.
If the magnet has worked, then the mixer is good, at least it will not be eaten by corrosion in a couple of months, so you can take it.
