Mind you I wouldn't pay ~£280 quid for that "iffy" solution. You should get a good a Mesh system to cure your wifi woes. £100-170 will sort it forever. Or there are even cheaper solutions that may do it for you.

I do not work for VM. My services: HD TV on VIP (+ Sky Sports & Movies & BT sport), x3 V6 boxes (1 wired 2 WiFi,) SH2 in modem mode with Airport Extreme Router +2 Airport Express's. On VIVID200, Talk Anytime Phone, x2 Mobile SIM only iPhones.
I have given up on most of the smart plugs I had, tried various makes, but all want to call home and will not work when the internet is disconnected. Also i need ones to work with Apple HomeKit app which most will not. Have now built some Raspberry Pi hardware to activate relays and written some software for communication between all the machines and Apple HomeKit. Most are also now connected via Ethernet which is a big win.
