They want premium but cheap out with usb 3 interface. So you don't even get the max speeds advertised even under ideal conditions. This is so overpriced.

When this comes down to $4.99 it will be regular price.

USB 3.0 5 Gbps exceeds the maximum speed of this WiFi chip. It does not support simultaneous multiband communication (almost nothing does), so you can only use one band at a time.
And even if it did, you're not gonna get 6.7 Gbps in either direction except for testing purposes. Internet connections require regular back and forth communication, so that peak 6.7 Gbps is going to be cut in half for most activities.

Wow. So much misinformation. Hopefully you are not confidently sharing such misinformation to other people. All modern routers and anything with Wifi7 support multiband. That is the whole pitch of upgrading to wifi7. So blatantly incorrect there. Second, unless you learned networking 4 decades ago, half duplexing is no longer present anywhere. Throughout doesn't get cut in half. Holy cow. Half knowledge so dangerous.

That is not the whole pitch, and it's a good thing it's not, because not a single device available to consumers today supports it. Please, find me a source that says it does. A Google search by itself, AI, and "just trust me" are not valid sources.

All current standard WiFi is half-duplex. Some companies have developed proprietary methods for client devices to communicate on multiple bands simultaneously. But it has not been implemented into any consumer routers yet, and it is not a mandatory feature on any clients.

EDIT: okay, I forgot about MIMO. It is a feature implemented on many consumer routers today and, if enabled and supported on both ends, allows for simultaneous transmit and receive. But this is still limited by the total bandwidth available per band, as it requires using separate channels for transmit and receive. Which was my original point that I forgot halfway through writing this.
