I bought this item figuring itd be far superior than the no name brands you see on ebay. Dont get me wrong, this product is great and well built. The aluminum has an almost chrome shine to it and overall it looks greatHowever, the product is the same as the aftermarket master cylinders you'll find on ebay for 50% less. IDENTICAL. Even the included bleeder hose kit thats included is the same paperwork as the non brand parts. Tuff Stuff has taken the standard aluminum part, packaged it really well, and sold it for well over double.The item itself has no markings on it from the manufacturer, no serial numbers etc. Its the same as the cheaper parts offered all over the internet. At the price I paid ($180 at the time) I was hoping for a logo or company name etched in the side to separate my part from knock off parts but this is simply the same product in a pretty box. Its almost offensive.
