Bests & Worsts Reviews from Amazon

I bought two and my nieces love them! As some other review says, buy PLA filaments and discard the ones that come with the 3d pen. It needs previous configuration of the temperature meter until it feels good to you (This means not too hot that the 3d pen spills more plastic than what you desire, and not too cold that it gets stuck or does not run smoothly). After that you are ready to go and have fun!
