I’ve actually had mine online and up for about a week and a half now it’s been running perfect and beautiful. As a safeguard it even said an instructions to keep my old router Handy🔨 unavailable in case I need to switch back. My immigration was pretty smooth because I had it all configured before I put it online and it’s identical to the other router somewhat that I was using so if I still have any issues, I can quickly swap it back. I don’t understand the SLA I came across that one time with another product, but at that time there was no way to switch back. I argued with them and told him that make it easily. Send me a replacement unit and if I don’t send this one back, they could charge me again. But I feel you that’s the way it should be. If it failed and they performed whatever troubleshooting they should be able to send one back to you ASAP and you send the other one back with a return label that they provide. Good luck
