Price performance good (25€ per clamp in 40 cm)_Quality mediocre to good.__Handles somewhat uncomfortable_Plastic not of the highest quality, but I am not an expert.__Be careful when spreading (spreading), do not pull too hard, otherwise the plastic may break, as happened to me. This is probably an exceptional situation - to clamp on the short overlap.__Normal gluing worked well so far.__The overhang of the mextall, as probably with all body clamps, is only 6.5 cm.__The question is how often one needs this size (40 cm).__Longer ones are noticeably more expensive, then the price difference to brand clamps pays off less.__Probably, regular clamps (F-Clamps) are generally more durable and stable.__mextall rails seem to be stable. Connectors for rails apparently not available.
Very similar product to other more well-known brands. The bar is 9x29 mm which ensures very good rigidity. I do not regret my purchase.
