Have this folding / Arbeitsbock bought due to other recessions and am not disappointed. It is very stable and keeps with security from the angegbene weight. The function of the role I found here very positive, so that 2 are 1 and not yet a further device is rum. The role can be easily adjusted in height, so that other sizes fit zwischer roll and rigid beams. However, a star I pull off because the package that was delivered quickly, however, was provided with loose parts. It took some effort to arrange for the items and build. by - about 30 min.- but otherwise very satisfied
