It was used when we had to remove the screw at only 12 mm in space. Because it was a flathead screw, it was impossible with other methods, it was finally able to remove it with this product, it was very helpful. It will be noticeable for normal use, but it is wonderful to have such a product for when it is time.
It is convenient to have one set when you need to skip the normal disassembly procedure and remove the hidden screws without removing the cover and auxiliaries.
