For 2.5 years of use, he fell once, from the balcony glazing: he ran into the edge of the lower part of the frame and the suction effect was broken. I caught it by the safety cord, went off, picked up the fallen off napkin holder, started it again - it went fine. I think I ran into the frame due to the fact that the wire caught on something and did not allow it to move normally. Make sure the wire runs freely. Of course, during operation, he makes noise. But I don't see this as a disadvantage.
