Simply the worst thing on the market. No connection with reality the company. Terrible drivers, no support for win 10 hotspot, the connection speed with the router constantly fluctuates causing stability issues. And with a wifi adapter from 2012 worth 15 euros, it has better performance than this one here.

One of the best for a USB stick in terms of speed for downloading, with full signal you have losses up to 2-3mbps MAX...
BUT when it starts disconnecting due to temperature, which happens frequently at 5Ghz, you have to wait for it to cool down and then reconnect (5 hours of continuous use on a 50 Mbps line). Nobody wants or simply does the following: at the back where the antenna is, there are two star screws, unscrew them and then with a flathead screwdriver, detach the top cover all around. After you do that, as soon as you remove it, you will see a thermal pad in front of you. You can replace it and significantly improve or even eliminate the situation... All of the above at 29 degrees Celsius... As for the price, I consider it to be quite high since we are talking about a mid-range USB stick

Unpopular opinion incoming.
I have had it for almost 2 years. Very good range, it doesn't lose significant speed and for simple use/navigation it's fine. With 100 VDSL on the 1st floor and my PC on the 2nd floor, right above the modem, I have 17 ping, 85 Mbps download, 10 Mbps upload.

BUT, ever since I started playing online games, from the very first use, I experienced lag spikes. My normal ms is 70, and during the spike it would reach 150-250ms. Also, recently it has been experiencing some disconnects (it's not a general modem problem, as my other devices have normal internet). I also had the issue of it disconnecting and then not being able to reconnect, even though I entered the password correctly twice. It would say "could not connect to X network." I had to restart my PC to fix it.

Overall, it's a mediocre experience. There are options (e.g. TP-Link) at half the price of this one with the exact same features, but I haven't tried any others to have a more comprehensive opinion.

Really good wifi adapter for 802.11 ac connection on my laptop, which being old does not support this communication protocol. I consider it necessary to purchase a fast wifi adapter if you have upgraded to a VDSL line and do not have a telephone socket in your area, the 5 GHz connection is like being connected with a cable! Speeds of 45 - 47 Mbps download and 4.5 - 4.7 upload with a ping of 14 - 17 ms consistently in speed tests. Overall, a good value for money, I would recommend it.
I was a little concerned about its initial installation (it displayed garbled fonts) and I would not recommend installing it with WPS, but manually. The range is expected for the frequency that ac operates (5 GHz), otherwise for greater range it operates at 802.11n, with significantly limited speed at 2.4 GHz (26 - 32 Mbps).

There is some incompatibility with certain WiFi channels in the 2.4GHz band at least. Otherwise, very good.

Excellent!! It catches full signal even in another room of the house, very fast without disconnections, it runs as if you are connected with a cable
