TEC 820

Work great. Very reliable. Adjustable temperature is a big plus.

Extremely durable and long living medium duty glue gun!

This glue gun has lasted several years and some of the harshest conditions that I think I could put a glue gun through. It just keeps on ticking and the thermostat does not lose its adjustability like a lot of glue guns tend to do overtime. My only gripe is that it takes 3 to 3 1/2 minutes to heat up instead of 30 seconds- that and it does not come with a second tip in case you somehow drop this poor thing straight on the tip and bend it up, you’ll have to reconstruct it somehow. Favorite gluegun out of 5.
