It does not require much pressure because it bends. You must first warm up the surface of the mobile phone and then use the tool.

It has a thickness of 0.25mm.
I used it to open a Samsung A5 mobile phone that has a stuck back cover. With a little heat on the cover to melt the adhesive, the tool worked perfectly. It went under the cover without causing any scratches or marks on the phone.

Very useful tool for anyone who wants to deal with mobile phone servicing. It has been tested on Xiaomi, Samsung, and Apple and worked perfectly. I would say it is a professional tool for both beginners and professionals. Very good quality made from good material that will not easily slip from your hands and will save you from unwanted situations.
