The only thing wrong with this workbench is "Black & Decker". Apparently I received a "Monday-Workmate": totally warped frame, screw / compounds do not match. This and the warped frame has precisely this Workmate no stability. Detailed assembly instructions? None; it was settled with glued little picture of the Word Mate a cardboard strip. Length of paper strip: 50cm! ! Toll! Somehow I have the feeling that this product from the workshop of "Candid" originates. Obviously, had the powers in South Asia Oast where Workmate was manufactured anscheind, a bad day or they have anything thrown. In any case, this was an absolute bad buy. Black & Decker I have been accustomed to a better quality. Emphasis is on: Up! In summary: Very lousy Abele quality; and that is still expressed very friendly. Was not worth the money. Paid for this is still too expensive!
