Nitro HD Accessories - xda-developers
Here you can see some talk about screen protectors and 2 reviews on the SGP case.
While I do think the SGP case is good enough, it's not perfect.
Same with the Realook screen protector. It is crystal clear, but doesn't seem to stay perfectly sealed on the edges.
If I got another screen protector I'd probably go with the Skinomi (Dry Install) screen protector for the LG Nitro. (NOT
the Optimus LTE. Slight difference here)
