I might have to try that. I used the Spigen EZ Fit immediately after peeling the film off my phone, and still managed to get fuzz underneath the screen protector. I tried again with the second one, in a steamy bathroom and with my headlamp on full blast to see any dust, and somehow got cat fur underneath. So I’ll either try that LK one or pony up the money to have Apple install the Belkin one.The LK one with the dust free fitting box worked great. Still not 100% on no black border as you can see the edges, but it's staying on.
