[EX Q]: This screen protector is great where privacy is concerned.... but it already has a crack going from the bottom to nearly the top it. I have only had this screen protector on my phone since Monday and I am super OCD about my phone and not dropping it etc. I'll still order screen protectors from Amazon, but probably a different brand.

[EX Q]: Make sure you buy the warranty. I did not, and this router worked great for about 1 year and then starting having issues. Everything in the router admin page looked fine, but we started having constant internet connection issues, and the LAN ports started failing. I have to buy another router now, and it won't be this one.
