This is the Outdoor Gourmet 4 oz. Stainless Steel injector available at Academy Sports. Maybe others have had luck but for me it fell apart on first use. I'm going to post Q-view but it's kind of out of focus. Problem. The needle end comes off. This is where the needle holder attaches to the main body. There appear to be threads on the interior reservoir, but there are no threads there the needle holding assemble attaches. As a result under pressure the needle assemble falls off. This is so basic that unless I am doing something wrong, I would think that EVERYONE would return this. Here's the Pic. I'm going to return this, of course. But can anyone recommend an injector a little more rugged than the Outdoor Gourmet?
