Often buying Stanley tools, I admit that I have always been pleased with the excellent price / quality of the brand. This level is even higher quality, the frame is very solid and fully dense metal, everything exudes quality pro. Magnetic (fits perfectly on the metal) and grooved, we can even measure the real angle with the rotating bubble. Only downside: a bit short but it's the detail because the measurement accuracy is there. In short for the price, is a hundred times better models of large areas, I highly recommend.
