The -:
No instruction in French and English record very badly explained (and story) can make the assembly / disassembly of quite tedious fans ....
Overall design .... pretty cheap to do over time ...
Plastic blades ...
In short:
Primarily professional users, these will be perfect 4 fans to ventilate a place like open space or offices. Nevertheless it will spare the majority because their plastic design is rather "cheap" ...
