I received this item at a discount in exchange for my honest and unbiased review. Unfortunately, I probably won't have the opportunity to get into welding for a few weeks. This review must be published quickly to comply with the convention. Caliber made of very thick and durable steel. Angles and divisions are accurate. The size is convenient and comes with a soft plastic storage box. The kit comes with a short and easy to follow guide that fits in the case. Metric and US measurements are on opposite sides. The only issue I have with the quality of this item is the very sharp burrs (see photo). I cut myself on inspection. It's easy enough to remove burrs, but for the advertised price, this item should be burr free. This is a new product, so with better quality control, it should become very popular among sellers.
