    Easy installation but that's about it! It disconnects all the time (specifically, it disconnected and ultimately froze every 5 minutes!)

    Quite a good product and at a good price for the job it offers. I have had it for 9 months and it has not stuck even once and it does a very good job

    Attention! This specific version (V4) does not support Windows 10, the company has not released official drivers. If you want it for Windows 10, purchase version V5 and above.

  • The functionality is excellent but its drivers are problematic. For a while, I was getting a blue screen with a reference to 'athurx.sys' every time I plugged and unplugged the adapter from the USB port of my PC, until I decided to replace it.

    Easy installation, within 3 minutes with the disk. The tower is in the next room and the signal is full. The speed gives me the impression that it is wired. And on the upper floor where I tested it, 4 bars of signal with the same response on the internet. At first, when I opened it, its size made me doubt its capabilities, but in the end, I was wrong. It is worth every penny and more!

    That I bought it and installed it. Extremely simple. It seems to work just fine. I haven't tested it or it hasn't been long enough to see any other issues, but as an initial impression, it is very satisfactory.

    I will come back after extensive use. Without having tested it, but for simple use, it does its job just fine. It doesn't disconnect and there are no other problems. I use it on 2 different desktops and there is no problem at all.

    It does its job perfectly and more. No disconnections, excellent range (the router is one floor below and I have 4 fixed lines).

    It's worth it until the very last minute. It's like having a wired connection. My house gets 5.9/0.7 and this gets 5.9/0.7
