For years I use this technology to free myself from cabler whole house. I started by 200Mbits models (Devolo AVsmart more Bewan Powerline) and then upgrade them with medium range models in 500mbits TP-Link. I then invested over 350 for 4 of these models 1200Mbits ... Frankly, I would have broken my leg ... Under the same conditions, 200Mbits Devolo is the 500mbits TP-Link was posing HD video with fewer problems .... a shame. These 1200+ are perhaps CPL good for those who do not have experience with the previous version, but with the experience and compared this model has a quality / price execrable.
