I do not know the durability, but I feel that accuracy and build are equivalent to the price. Because it is low price to arrange a few items to learn how to use it is very helpful. Personally, since the "monotaro" notation inside the dial gauge is not preferable from outside as it is, it is italic alphabet and "MonotaRO" etc. at first glance if you do it at first glance, I thought that I would not feel cheapness.
Regarding accuracy, I think that it is okay. The repetition system will be okay. I think that the attached dial gauge is very stable, looking after using it alone. I feel that the movement of the gauge head is not smooth compared to famous manufacturer products ... I just screw in the anvil fixing method, so I feel that the durability is low ... only for measurements of the same size When using it, since crunching is troublesome one by one, I thought that it would be still better if the storage case was designed to be able to keep it with the dial gauge attached. If you can not keep the dial gauge set, you should be able to compact the case more compactly! From the overall contents, it seems likely that you can make it a little cheaper? In the scenes using the utensils that said this way, it should be used for work that requires a certain level of precision, so if you use it frequently, we recommend you famous manufacturer products as well. I think that those who use it on Sunday carpentry or about hobbies are necessary and sufficient for this product. However, in order to increase certainty, I think that it will be more time to use measuring time than necessary.
