It good for small DIY projects but not for heavy duty work. If u have larger surfaces to stick, by the time the glue comes out heated and u apply on all the corners, the glue starts solidifying. Then dosent stick. The heating and melting and application process is very time consuming. Add to the cumbersome power connection. The glue stick will finish very fast. The amount u get to stick is very little too. I think ur better off with conventional glue anytime. Good old fevicol and similar glue comes to mind. It will be messy but at least it will stick and get the job done. Thumbs down on this product.
