Best Buy and Amazon.com publish online reviews for WiFi range extenders, as of 2015. Both sites display critiques of multiple models. A rating based on a five-star system accompanies each review.
On Best Buy's website, positive comments about WiFi range extenders mention that the devices are easy to set up, have good range and are reasonably priced. Criticisms include slow signal output and password problems.
Five-star reviews at Amazon.com appreciate the significant increase in signal strength. The extender is also unobtrusive in the home. However, single-star reviews state that the device functions intermittently, and users must reboot the system often.
