Review on Innovative Products of America IPA Tools 80287-Way Flat Pin (Spade) Towing Maintenance Kit – Patented, Black by Scott Ward

Maybe I'm using it wrong but the tester on my truck is upside down, not critical but stupid. The connector cleaner teeth are too tight, I feel like I am about to pull out the connector. I think (that I used) a small piece of fine mesh sandpaper is sufficient. It's very expensive for what it is. female end, the file is not suitable for cleaning the female end. I get it and I think the tools are a great idea, but they don't work for me.
