I bought a screwdriver for radio-controlled cars. a screwdriver can not always unscrew the screws immediately, you have to tighten it like a regular screwdriver, that is, loosen it. also when twisting. but dismantled the laptop, and all the screws succumbed immediately, so it depends on what to take. I like it anyway. I am satisfied with the purchase.
Attached some photos to this review to help readers visualize the product.
