are caused on the one hand that this cumbersome folding complicates the Gebraucvh because the collecting bag was again this time on the other side, but then I must recognize that this number (500) is being offered at an extremely competitive price. So I take a little more time for the neat person and not fold n for these collecting bag to the other side in order, but "Puhle" the bad punched mounting straps tedious apart so this Esslätzchen can not slip.
