Bests & Worsts Reviews from Amazon

Almost all of the gauges are about 1/2 a size off, some are a full size off, as measured by my new PepeTools Ultra Precision Steel Ring Mandrel I bought at the same time. All these gauges look to be cast metal with a molding flange which hasn't been trimmed inside every one which decreases the inside diameter and also scratches your finger when you try to use any of them. These flaws make this item worthless since you can't get an accurate measurement with any of the gauges.
