The range is excellent. This adapter picks up WiFi networks I've never seen before and with surprisingly strong signals. The range is especially good when I stick the adapter to my window with the included suction cup. But I get 100% signal strength connecting to my home's WiFi even when the adapter is clamped above my monitor.
The adapter is fast! It's faster than my access point. I tested the speed with iperf3. The other computer was connected via Ethernet. I measured 250 Mbps, which is the best my access point can do. I saw someone else measure 940+ Mbps.
It's not perfect, however. The specs aren't detailed enough; they don't say whether this adapter supports MIMO or MU-MIMO. It's sorta big and bulky, though its size might be needed to achieve its excellent speed and range. Also, if you're a Linux user, the driver's likely aren't included in your distro. The drivers are easy to install, and they work well, but the quick-start instructions don't tell you that you need to go to GitHub to get them. Also, if you're a Linux user, you need to know your way around the terminal (a little bit) to install the drivers. Beyond that, the included quick-start guide is terrible. It explains how to install the drivers on Windows XP. I suspect most people are buying this to use with either Linux or Windows 10. It's a bit eyebrow-raising that their quick-start directions are so out of touch. Also, it uses blue LEDs. I don't like blue LEDs, because they can interfere with sleep.
This adapter isn't for everyone. But this is a good pick if 1) you're a computer professional or power user. Or 2) you need its range or speed, and you don't mind its size. Or 3) You're a Linux user looking for something high-quality, and you don't mind using the terminal a little to install the drivers.
If you're the right kind of customer, then you're gonna like this WiFi adapter.
Even in labs, this device could not get results that other much less powerful devices easily got.
It's not until I decided to test it as just a normal means to connect to a wifi network when the problem became obvious. Its connection strength is fantastic, but the quality is horrific.
It's much easier seen in an online game, a few seconds of clear movement followed by extreme lag, almost to a drumbeat. Same with even a zoom / skype call. (The Notebook right next to it, connecting to the same wifi network has no problems with either of these). All rendering the connection quality useless in many applications.
It would also at times just completely stop finding any networks, requiring to plug it out and in again.
This is not the kind of problems expected with such an expensive product.
Other issues:
Does not work on Linux Mint, using the latest and even older drivers and following various threads around similar issues. Mint doesn't see it as a Wifi Device, but weirdly can be connected to virtual machines.
Kinda works on Kali, but several features like focusing on one wifi channel doesn't work.
