Hello alszu, initially makes this tool really fun! Everything you need for small repairs on your bike is tuned here! The beautiful and stable metal casing protects the tool before verdrecken and unnecessary damage. However, I am more likely to use the screwdriver noticed that especially the chain tensioner is always relaxed. Because, unfortunately, also helps turn continues the Allen screws only partially what. :( For normal use for bike repairs (and not the "handymen"), but this tool is great and gets me full 5 stars!
