very bad, can't be used at all, vasted money
After I assembled the frame and I could not get the cover blanket over the edge , I disassembled the frame and looked at the manual once again. I noticed that the assembly part "D" and "E" is the same part (with different label on it), but it should be diametrically opposite - for it's on the other side.
Also the size of the cover blanket is too small by both sides, the width and length... just can't get it over the metal frame :-(
As I see it, it's 16€ wasted, not providing functionality.
