Sorry about the Brando SPs Grog... I'm using one right now and don't have any problems using my N810 outside at all - my husband is using one on his N810 too and he uses the gps in the car without issue. Are you positive that you ordered the anti-glare? I know that they also sell "Crystal Clear" SPs. I'm having a hard time imagining what more anti-glare would look like for the Boxwave's vs Brandos. Regardless, I'm glad to hear you're happy with your Boxwave SPs. I'm very sorry again that I referred you to a potentially inferior product.
