I bought the Supershieldz for LG V30 Tempered Glass Screen Protector when I pre-ordered my v30, there weren't many tempered glass options at that time and no reviews aside from the sponsored BS ones (you know the deal..... "10 Best Tempered Glass Screen Protectors / Cases / Accessories / etcetcetc" websites that all have affiliate links to Amazon for the stuff they're shilling).

I've used Supershieldz screen protectors before with no issues, so I wasn't really concerned about getting a bad product.

Top to bottom, coverage is perfectly fine (IMO). Side to side, not 100% perfect. Where the screen curves to meet the bezel there is a small portion of glass exposed, but to be honest I really don't care since the case I bought covers that portion.

BTW, this is the 2nd Ringke case I've used (had one on my previous v20) and I can highly recommend it. Ringke Onyx for LG v30
