I've been using it for well over six months. Everything was OK when I personally set up both blocks. So, I set out to increase the range of the Wi-Fi network. TP Link's website features a gorgeous diagram detailing the system's distribution of a signal to four Ethernet receivers via wire for conversion to Wi-Fi from the main unit. However, you cannot buy individual blocks of the WPA4220 anywhere. When I contacted the manufacturer with an inquiry, I was told that I needed to purchase the specified amount of kits rather than the WPA 4220 block individually. And I have to go out and replace the primary building blocks. A bit of idiocy. In most cases, I find that anything above a 4 is unrealistic.
