I have this tool that I haven't used because I don't understand how to use it. From this video, what tools are needed to open a curved LCD

This machine is only for curved screen or work with flart screens? why is 5 in 1?

Mmm. Is there something wrong this machine had? I mean when you heat-up the phone screen is in below so when the heating over the phone is flip over and then separating process is do, the question is that machine is useless right? What I mean is what point you use that machine if you don't need to heat-up the phone?

Price ?

Where can we purchase what is the price? I want to market this product
