I ordered this pen for my son in May. We made really cool artwork with it and he really loved the pen. Here it is October and the pen will not stay hot enough to do anything. I have tried to troubleshoot this issue but it is still not working. It does have a warranty so I have emailed the company to see if we can resolve this issue. I’ll update my post once I have spoken with someone from the company.Overall it is user friendly, really easy and fun for the whole family to enjoy. I would recommend this product.
