So far, all my expectations were met. But you have to make it clear that this adapter, any brand, not a complete substitute for direct wiring or wireless networks are dual-band.
This means in concrete terms, who are the NAS or the server in the basement and want to make a backup of his system, or often moves large volumes of data will probably have fun with these adapters.
I run both 200Mbit and 500Mbit adapters in mixed mode, all of TP Link. According to the InfoTool mitliefert the manufacturer for Windows, I have there data rates between 160Mbit to 250Mbit.
The adapter run all through various phases with me. I do not use phase coupler!
The real data throughput is the adapters with 1000 Mbit LAN connections in my case at about 20-35 MB / sec. For the smaller adapters offer only a 100Mbit port, the data rate is approximately 8-11 MB / sec.
I take care with these adapters my TV and BR player (also for streaming from the NAS), a desktop computer and in the garden, I use one of the TP-Link adapter with integrated wireless access point.
This setting runs now about 2 months without any noticeable disconnections, over the wireless link data to be sent from a server regularly, so I could see if there were disconnections.
My house is Installation of 2005. selfsame building I also have in my parents' house, the installation is from the 1960s. However, there decrease the data rate down to about 85Mbit.
Also from the reach of the adapter I'm impressed, even in the outbuildings (garage, pavilion) still comes into being a good connection.
Conclusion: Those who want to bring the Internet, IP-TV or video streams from A to B or C, it may be quiet it a try.
Significant noise of the adapter or heat generation, I could not tell.
