A comment
Apparently, the Bonati company is one of the first who began the production of magnetic latches for interior doors. I have had such locks for about a year now. Their cost is certainly not budgetary, but so with any product that only comes out on top in demand. At first, when I just bought Bonati magnetic latches, I was terribly disappointed. The mechanism did not create the impression of being reliable. Some kind of flimsy plastic latch, in addition, having a noticeable backlash that has not yet been installed. However, the installation of such a lock did not present absolutely any problems: I installed the groove cut out, measured the answer, cut out the groove and mounted it. However, there are several nuances, first of all, you need to accurately position the latch and the overhead bolt, the door leaf is offset by 2-3 mm and the lock will not work.
pros
Noiselessness, reliability.
Minuses
High price, meticulous installation.
