On the one hand this is a comprehensive set, from a usually reliable brand, which offers great value for money. On the other hand it is not all great quality. When we tried the outside caliper (the bowed one) we found it has uneven tips, slanted at irregular angles, so the measurement can be incorrect - depending how you apply it - which kinda defeats the whole point. Overall, it's still good value. Just don't use any which are inaccurate. What should we expect for the price? You also need to keep the items greased, else they are prone to rust if you are in a salty or damp environment - we happen to be by the ocean...
