Title: Worthless Junk
Review: I bought the Arrow TR550about a week ago. I have other glue guns but needed one right away for a job I was doing. This tool is an absolutely worthless, useless piece of junk. It may be OK for the occasional hobbyist, but not for any serious use. Trigger won't push much glue through the chamber and out the nozzle, unless I push the glue stick with my other hand. Waste of money, waste of time. It's going back.
