Pros and cons

Pros

Two frequency bands give buyers a choice between the listed 5 GHz and 2.4 GHz peak rates.
The adjustable external antenna offers more positioning flexibility than a fixed, internal antenna.
The listing names Windows versions from XP through 11 and macOS 10.9–10.15 as compatible.

Cons

The supplied macOS compatibility range ends at 10.15, so current macOS support is not established.
The 867 Mbps transfer-rate field does not describe combined band speed, and the adapter cannot exceed the router's maximum speed.

Customer feedback describes positive experiences with ease of setup, speed, signal reception and build quality, but connectivity and reliability reports are mixed. Some customers report disconnections, and the summary includes a report of the adapter stopping daily around midnight to 1 AM. Compatibility and driver experiences also vary, including reported trouble with current Mac systems and Linux drivers. For desktop buyers, that makes exact OS and driver support worth checking, while the adapter's listed dual-band rates and movable antenna describe its intended capabilities, not proof of consistent results.
