A simple and inexpensive established. I knew the product to have a more complete already. This one, purchased for use vacation, is simpler, equally robust and very good price performance ratio. The front board is fixed, it was she who serves as front cross (instead of the metal cross other models). Only the rear plate slides: it is secured to the clamp screws, and can not be placed in several positions as on the other models. The planks have a groove on the song to tighten the tubes. Mechanical folding is identical to that of the other models. Book in kit, easy to assemble (count ten minutes). Supplied with a key to screw the 4 bolts securing the boards. Quality quite good. Only features are smaller than the more advanced models.
