Pros and cons

Pros

Two frequency bands let buyers choose between the stated 2.4 GHz and 5 GHz wireless rates, subject to router and network conditions.
The adjustable external antenna can be repositioned to suit the adapter's placement.
USB 3.0 Type A connects directly to a compatible desktop or laptop port.

Cons

This is an 802.11ac adapter rather than a newer Wi-Fi 6 model.
Actual wireless throughput and coverage can vary with network and environmental conditions, so the stated band rates are not guaranteed real-world speeds.
