Amazingly fun to use!You will need a set of metric Allen wrenches, and either a wrench or players, for assembling this.I did have to make a small roller spacing adjustment, but it only required a screw driver.Works beautifully, seems very durable, easy to use, and so much fun to use!FYI:Material does not exit rollers flat, it acquires a wavy curl.I love it, and am so happy, that I finally bought it.:)
