Switched out my bearings in a couple of hours with this and the bearing press tool.  I had never done it before but knew I could with the right info and the right tools.  I got this and the bearing press tool from Amazon.  that gave me the right tools.  I used the inclosed instructions along with product-specific repair videos on YouTube and essentially this was as easy as changing bearings on my old skateboard.  Just a little added size and electrical instructions.  If your spin cycle is loud, this is probably what you need.
