Unfortunately, this product has no relation to the Stanley name. It is of low quality. The metal is quite thin and not sturdy at all, while the depth gauge is made of plastic, as well as the sliding and tightening wheels, resulting in the flexibility of the depth gauge and the risk of breakage. In fact, once when I accidentally pulled the wheel with the safety on, the wheel came off from the hook that slides, which is also plastic and fake, in fact plastic. Overall, one can measure with it, but it is definitely not worth the €16 it asks for. For this money, there are much higher quality calipers available.
