Key USB3.0 wifi Linksys AC 1200 WUSB6300

I am very satisfied with this product.
I use it to connect with a tower and I feel bbox identical flow rates compared to RJ45 cable that I used before. After the turn is not far from the bbox but I had heard so many negative comments about the wifi key that I was quite worried.
I tested 2.4GHz and 5GHz, table and reception rate are slightly better in 5GHz but the 2 modes work very well with a stable connection.

The key is a little large compared to the mini key that are now, but that's the price to pay for having a good sign I guess.
Very good buy.
