I can only warn against a purchase: Rarely seen such a scrap! Totally useless! My angle: (Flex) does not fit; unfortunately only realized after I had half an hour. my life wasted with the assembly. Instructions so bad that an assembly will be delivered already becomes a challenge. To assemble you need 2 different Allen sizes, 3 different sizes end wrench (including 1 x size 14, which no longer really there!), And a slot screwdriver. Product returns immediately.
