I am still trying to understand why this site is flagged as potentially harmful. I have been using this product for years and it is amazing. There is nothing harmful about it. As a matter of fact, ASUS works with the developer of ASUSWRT-merlin directly.
Whoever rated this site badly doesn't know what they're talking about. This is an open source development group that makes/modifies secure router software for ASUS routers. Super well organized and a great project on github...
