I bought this 'TPLink X55 3 pack for my parents house as wifi did not reach the other end of the house. Even with an extender the signal/speed was lackluster to say the least (Buffer central). Setup through the TPLink app was intuitive and easy. Now their lounge gets 160mbps which is obviously more than enough to stream to their smart tv in 4k as well as running other devices I.e. phone etc at the same time. Such a relief that disgruntled conversations of poor wifi is no longer a part of my fathers conversation repertoire.
