Repairs Universe is located in the USA and they have this LG G Pad 8.3 Screen Replacement Most likely will get to you in a matter of a few days rather than a few weeks shipping from China. If that's what you are concerned about. Cheers!
I would totally use a heat gun or a hair dryer as the adhesive holding the LCD to the Touch Screen in gonna need more heat than what can be generated from the iOpener.
