Summary: Total piece of crap. Mechanical design is frail at best. Unpack-aged mine and it immediately broke when I unfolded the USB connector. I was able to connect it to my laptop using a USB3 port, only realized 177 Mbs speed at 10 foot distance to a Buffalo 802.11AC wireless router (WZR-1750DHPD).

Summary: Did not see the speeds promised in a good environment (less then 10 feet of separation between the host computer and the wireless router.
Pros: Did not realize any of the speeds advertised. Using a Buffalo WZR-1750DHPD Router with this client adapter mounted in a USB 3 port of a new laptop. Highest transfer speed indicated was 170 Mbs.
Cons: Adapter has a fold out design, broke immediately when removed from packaging. I broke on first attempt to unfold it. The design is frail and I cannot believe any mechanical engineer would sign off on it to last any amount of time.
Summary: This is an alteration to my last review. The issue I was having with it dropping connection and not being recognized was a USB 2.0 issue. I moved it to a USB 3.0 port and have not had a drop in 10s of hours since.
Summary: if noticed that vertically all generic 11AC USB addon's to date state up to 800+ speeds without making it clear that Only 11AC adaptors with a USB3 interface can actually reach these speeds. I'd like to see dabs provide a clear and bold this product is using a USB2.
