@realtimesave, V1 Switches don't need a modchip, all that is required is a Trinket M0 or RCM Loader and a jig to put it into RCM mode. For the V2 Models, this requires a glitch chip to put the Tegra back into the recovery state, since it's locked out.
It's easier to remove if the screen protector is made out of plastic. Whereas glass is a lot fragile to handle. Plastic is more-so the cheaper option, has a short lifespan but doesn't have the most protection against deep scratches; rather light scratches.
