    31233 is rated 4.5 out of 5 by 2.
    Rated 5 out of 5 by from Quality complete kit The tool and directions made this easier than any other wire kit that I’ve used. I’m not a professional, these are by far the best wires that I’ve put together. The quality is worth the little extra cost.

    Rated 4 out of 5 by from great features Got the distributor ends I expected, but the image showed straight plug ends. Made them work regardless. Wasn't pleased about that.
