The cage is very stable, height adjustment holds good. The housing and base are made of shiny plastic, stability is good.
In my copy, there are minor difficulties with the lowest level, the selection is possible only from the second stage of. From the off state, he does not start from the third stage from it slower until it finally shuts off completely. As long as it works, I do not mind this error.
FIX: The bug with incorrect switchable first stage (from other reviewers) has done with me by itself. After a few days I was able to turn the fan on the first stage, since there were no further problems. Tip: just "test" for a while before sending back, if the first step does not switch.
UPDATE end
The only negative aspect is the noise in the oscillation. On level one bothers me neither rotor noise nor air noise when sleeping, but unfortunately the "toast" when changing direction. Ultimately, it is more comfortable to sleep next to the fair stage two, the better masked the sound when listening to the rhythmic clatter.
Nevertheless, even in comparison to my previous fan, a very good device.
