My two sons are happy to go with their longboards, weather permitting. Here one tries of course times other wheels or settings of axis or it must go to a ball bearing to be changed. After repeated use of domestic toolbox and search the appropriate wrench the desire came on for something Tranportablem what one can sometimes put into the bag. Here offers this tool, which even includes a small screwdriver, which is inserted into the tool for the purpose of transport. All required wrench sizes are in - housed tool on the go - in reality but slightly larger dropouts. The usage is simple and the quality in my opinion for the price fine. And now everyone has "his" tool, on which he has to take care and maintain it. I highly recommend this tool.
