I purchased this item solely for the cordless aspect. However, the truth of the matter is that this item is not a cordless glue gun. You must plug the glue gun in to heat the glue, then you can use it for UP TO 5 minutes unplugged. The projects for which I use glue guns take much longer than 5 minutes, so the cordless aspect of this product is completely useless for me. In addition, while the enclosed instructions indicate one size glue stick, the packaging indicates another size. If you use the size indicated in the instructions, the glue gun will not operate; use the larger size glue stick indicated on the packaging.
