Have the part purchased in October 2012 and now used for the fourth wheel change. The device adjusts its service because a carbon brush is broken. Now a vain attempt to come to a suitable carbon brushes, which is indeed is a wearing part. The company Primopet as a seller is indicated on the impact wrench. Call there with the information: We are sorry, the warranty has expired. My answer: It does not matter, I want to buy from you ever even brushes. Primopet: We do not sell something, and I do not know where they get that. Since they are now left to their own !! Is not it great that and throughout the Google I find nowhere carbon brushes for the red fox impact wrench. For a device that I can throw away now, I can not be a star. But a star you have to click yes least
