This 100W heavy duty glue gun is very well made and way better than I was expecting. I thought it would be like aa normal sized glue gun with the extras it advertized. Boy was I wrong! This is very large, making it perfect for my husband who has huge hands, the glue sticks are larger around and longer, there is a trigger pull and an on off switch. there is also a guard around the nozzle to prevent burns! This really is a better glue gun all around and perfect for the wood crafts we have been doing. This also comes with a 30 day return gaurantee... I love this thing!
