Anyone know of way to repair Touch ID?

Hi, i’m looking to repair the Home button on my iPhone, I know very well, that with the iPhone 7-8 Plus, when you replace the home button, it no longer works in any way at all. But Very Recently Manufacturers like JC, BFX, and Shalou are making home buttons that work like a real Apple (Probably Foxconn) home button with the haptic feedback and response, etc. I also come across this tool made by JC called the FT-1, have any of you got any experience with it. It claims to be able to R/W home serial information, back to a JC home button. Do you guys have any thoughts, or is it just false marketing?
