I had been wanting a button maker for a long time. I finally gave into this desire recently and have not been disappointed. This machine shipped quickly and was simple to assemble. It is missing one small pin, but I am able to get it to work without it until I can get or make a replacement. It_ simple enough to operate that my older two kids have been making buttons independently. My four year old is able to use it with help. Everyone is loving making buttons. I did not like the paper cutter that came with it_t was difficult for me to use and had an exposed blade making it unsafe around kids. Overall, a great investment. (Picture of the missing pin.)ML
