I've been wanting a multi-size button maker for awhile for something fun to do in my spare time. Money is tight so I didn't want to spend a lot. The price point on this one fit the bill. I would have preferred all metal button backs. Originally, I thought this set included all plastic backs, but it has 50/50 metal/plastic button backs for all sizes. The plastic ones are nicer than I thought, although I still prefer the metal ones. The machine seems pretty sturdy and well-made. It should have taken about 10 minutes to assemble and make the first button, but the instructions are TERRIBLE. They were clearly written by someone who does not speak fluent English. My brain felt like it was melting trying to make sense of them. However, after quite some time of trial and error, I was able to get it to work. My main issues were: For the first push (A), the pins on the lower piece are not meant to go through the holes. When you move the tray over for second push (B) - applying the button back - it moves so that the pins DO go through for that push. Secondly, I had a terrible time getting the upper piece removed so I could swap sizes. It took a lot of pull - A LOT - but it finally came off. Once I figured it out, I made a couple quick buttons. It was easy and quick and they came out perfectly. I did order 90lb paper to go with it. I also made a template on PhotoShop for the different sizes. That way I can size them perfectly and cut them out rather than use the circle cutters that are included (difficult to use and basically worthless IMHO) or spend money on circle punches. The included book is okay. It was nice to have some things ready to cut out for trying out the button maker, but they are nothing I'd use otherwise. A book with a variety of general themes would have been nicer. Overall, I'm pleased so far, but will definitely update if I run into any issues.
