I bought this product to add to my powerline network which consisted of 2 POWERLINE AV ETHERNET ADAPTER
XAV101 from Netgear. To be honnest, I was afraid it wouldn't be compatible as not from the same brand but it worked as soon as I plugged it in. No need to pair, I got an internet connection straight away. It was hard to find any info online on whether they would be compatible so I can't say about other brands but it works with my 20 mbits Netgear Powerline Adapters, that's for sure!
I live in a house from about 1890 so the wiring must not be that great but it still gives me nearly 3 times more speed than a wireless connection when I connect to my Nas Drive (QNAP TS-210) which is downstairs, plugged into my Sky router.
I had spent much much much more on my Netgear pair and now don't see any reason of spending so much again. This TP-Link Mini Powerline Adapter is great!
And it says on the box there's a 3 year warranty so I'm quite confident it's durable!
Had never heard of that brand before but I'm very satisfied now!
Enjoy!
