I bought that exact item and it was horrible. I returned it. I am one of the people that gave it a 1-star review, in fact.
I don't know if mine was defective or what, but it didn't work at all. I couldn't get it to tag correctly and it finally jammed up completely and broke inside. And I used to work retail and use one of those all the time so I had a pretty good idea of what I was doing! No matter what I tried, it just jammed and jammed and jammed. It was extremely frustrating.
I've thought about buying another at a local shop to see if I had better luck, but I got so frustrated with the first one I haven't tried again. I think I'll just stick with Elmer's.
