ixf cheap Chinese cranks. Are they worth it

For someone that doesn t exactly take it easy on the trails can I fit and get away with riding like I do with cranks. I must say this experiment makes me nervous. there are numerous thing that could go wrong. I tried to find information out about these cranks, but I couldn t find and videos that gave me the information that I wanted. I just hope I live to regret my decision and it doesn t end in tears. wish me luck
