Simply plug it in, WPS pressed at the Fritz box and then on the repeater. It took less than 20 seconds for there was the small part online. Simple and very practical.
The LED indicators are practical and not covered, what you need, they indicate.
However, now comes my review that has led me to the point deduction. The repeater is a straight line about 3-4 meters from my Fritz box, this is in the lower hall - one floor up, also separated in the hallway and only by a staircase, there is the repeater. Here it reaches of the alleged 300Mbit / s maximum 60-70 Mbit / s. This is clearly not enough.
Actually, it was intended as a stopover to tie the middle floor. In the attic is a Netgear Bridge, which achieved the same performance despite twice the distance to the Fritz box.
Conclusion:
For extremely short distance and small benefits of TP-Link repeater is sufficient. He is stable and is very easy to set up. No German instruction.
