Asus have put out rubbish for years and chosen to back it up with appalling service/support. The logic seems to be if you make it look like a transformer wiped its arse with a PCB and put some (sometimes barely functional) RGB lighting on, then people will pay over the odds for it, you can string them along with promises of fixing basic BIOS issues as long as it overclocks OK and just ignore them as soon as you launch a new SKU. If/when they do send you a board back, you can either refuse the RMA because it's (insert day here) and you don't do RMA's on (insert day here) or send out any old non functional junk and see how many times before people get sick of it. Why do they get away with this? Because the one thing they do better than other players in the market is bribe market well with 'influencers'. They did it with the networking side with faked FCC certification, ignored known security holes for years till a very large retail partner stated they were going to pull the brand and were fined heavily in the US/had to agree to decades of external audits. The motherboard side is equally messed up, BIOS' plagued by fundamentally basic issues and then support dumped as soon as they've churned another version out. Asrock/Gigabyte/MSI/Supermicro tend to be a better bet overall (an extra few hundred Mhz vs weeks of no product because of crappy RMA service)... unless you have a pet transformer who prefers Asus to puppies.
Many years ago ASUS were a quality brand and worth paying a premium for, but for at least the last decade that's not been the case on RMA's/support and the overall quality seems to be a secondary focus to branding/marketing, what happened to making a good product that justified a premium price and standing by them?
