no difference to 650+, in some cases even worse

... How do you say try making wise. I had been all adapters ranging from the devolo 80, 200, 500, 650 in use.
Hoping to my already installed devolo adapters 650+ performance to even increase slightly (118 Mbit / s) I looked at the 2 devolo brought 1200 adapter. The adapters are used primarily to distribute T-Entertain at home, Apple TV and to connect an Xbox. Unfortunately I had to as some other reviewers notice already, this is the performance almost identical to the 650'ern. To a 500 Wifi adapter even slightly worse. This is the first I'm really disappointed with devolo because the marketing has probably prevailed.
