Ditto. Even the (in)famous WIFI 5 GHz chip has worked like a champ. I have upgraded to the AX88U just to have a better CPU and to continue using Merlin FW, but I had no regret during the five years I have been using it.High temps aren't really a problem for these routers. My RT-AC87U has been running around 90 degrees Celsius for the 4 summers since I got it (spring 2017), it hasn't skipped a beat and it's still running as a champ. I'd bet it would have kept running for 5 more years if it weren't for the firmware, which is the real issue.
