Excellent product, received as quickly as quickly buy 1 copy to be 2. It's already up there just to unpack and unfold. This one is very light and compact when you have to store it is important. By cons of aluminum folding key screw the other side and thus the abyss, I do not understand that this was not seen in the design. In any case it does not bother me more than that, too bad there have no other colors. The gray being out of stock zt too expensive compared to black.
