I have bought one and recieved it 2 days ago, it has solid hardware and it's price/perofrmance is perfect, but the wifi is strange, mine seem to work fine (speed wise), but while 5ghz can output 20dbm max, 2.4ghz doesen't go past 8dbm, I will be re-flashing the device today and checking to see if that changes, as for firmware, I haven't tested anything besides stock openwrt, but the aliexpress seller that I bought it from had many firmware options.
2.4ghz
