I’ll pose yet another question to answer your question…
What will it cost and what mechanical knowledge is required to professionally separate digitizer glass from the LCD?
There are two scenarios:
1. You’ve damaged your digitizer screen and want to salvage the LCD. You want to defy everything that you’ve heard about botched screen extractions. You’ve purchased a digitizer screen and LCD, separately, from two different foreign companies. The neither foreign seller can offer you instruction or even instructional video on how to do the repair. They’ll just say: “it’s easy.” Right, buddy!
2. You’ve managed to come across a local company that has the proper equipment, but wait…
The parts cost you USD$30.00 altogether and the company that will fuse the parts together, properly, will want $20.00 to do it for you. Under the circumstances you should have simply purchased the digitizer/LCD full assembly and spared yourself the runaround and backflips.
Scenario #1: has a failure rate of 9.5 out of 10 attempts.
Do you really own the 10 iPhones that you'll inevitably brick?
If you just happen run or own a repair shop, you just bought yourself 9.5 new assemblies for those customers, because the LCD was not broken when you got it from them. Will you lie to save your skin?
Scenario #2: It’s unlikely that you’ll find a factory that will repair your piece, because they’re too busy doing large volume manufacturing and can’t be bothered. They’ve invested in various pieces of industrial equipment that you’d never see or use, unless you have several hundreds of thousands of dollars to invest in such a facility.

Good luck with your .99 cents plastic removal and repair kit tool! You've been duped if you actually purchase such kit. They're sold all over the internet to unknowing, nieve and weary consumers, who are trying to save a buck with DIY, which is a wonderful ambition to have.
There are literally millions of online re-sellers of aftermarket parts that don't know much if anything at all about the products they sell and technical support is basically improvised. I'm sure that they'll keep selling the digitizer glass to consumers and make millions, but the consumer will always do a bad repair or unprofessional repair. When they sell the parts to a factory or manufacturer that actually has this equipment; that's a well-matched business relationship.
To sell these useless components is a SCAM! The irony is that the re-seller has no idea that there is a problem, so they'll keep selling them randomly and make millions. I almost purchased a digitizer glass myself, but when I asked the seller how to install it, he could not give a reasonable answer, but said " It's easy, just purchase it."
Fortunately I Googled and did my research. This is how I'm able to report my findings to you all, right here. I heart ifixit :)
