Query: Poor quality

First off let me say the packaging was horrible, a large box with 7 of these in them with zero padding. Of course they were damaged.Second, I unwrapped one that appeared not to be damaged, moved the vent blades and the blades fell off.I did not bother to unwrap any others. Set up to return within 15 minutes of receiving items.Glad other reviewers had better luck.
