"This extender makes impossible claims for a price that buys better, branded hardware."
The '10,000 Sq.ft Long Range' is a theoretical, open-air maximum. In your home, this device will extend a signal through a few walls at best, and using it in its primary 'Repeater' mode will cut your effective Wi-Fi speed in half.
Reasons to consider this product are few. If you absolutely need a simple repeater with multiple operating modes for a non-critical task and are comfortable with the significant performance and security trade-offs of unbranded hardware, it exists. The WPS setup is simple for those who avoid web interfaces.
Anyone seeking reliable speed, meaningful coverage, or basic security should skip this. For the same or less money, established network brands sell dual-band extenders with honest specifications, verifiable performance, and firmware support. This product's marketing is disconnected from its likely capabilities.
