So, I 've used this 3D pen 15 minutes and then went he unfortunately not more. He had suddenly no electricity more. But 5 stars is there anyway weilder dealer super fast back wrote and me a new move. Hopefully holds the new then longer because he worked total well and is beautifully finished. Faulty products there is always and if one Times a caught it dopey, will probably not all soon get broken! :) Can the pen hitherto only recommend. I will you at running! Thank you!
