Is that a yes then 
Here is a review on Amazon for the TP-WPA4220:
Size: AV600Style: Faster (N300 Wi-Fi + Passthrough) Verified Purchase
Impressive - easy to set up an works well - gives a strong Wi-Fi signal.
I bought these to give me Wi-Fi at the bottom of a 50m garden. I have mains power to the shed, but wasn't sure if these would work that far away - through multiple circuits/junction boxes, switches, etc. But they work fine - and worked straight out of the box. Plug them in, wait a couple of minutes, and bingo, it works! Very impressive.
And the Wi-Fi signal from the shed (which automatically uses the same ID and password as your main Wi-Fi) is so strong that I can use it in most of the garden - it reaches a lot farther than the Virgin router does! It's not very fast, of course, but perfectly adequate for normal use - and the remote plug has an Ethernet socket as well as Wi-Fi, so I could always plug the laptop in directly if I wanted to do some serious computing in the shed!
These are actually so impressive that I am seriously thinking of buying another remote plug to use as a booster in the kitchen or upstairs, as the plug-in booster we've got was never very good and has now failed completely. These are twice the price of basic Wi-Fi boosters, but work so much better.
