  1. wonderful product for this price

    Posted by Jason on 24th Jan 2017

    A solid router with very strong performance and a lot of features to explore. It is refurbished but looks like brand new, so I am really happy to have it to replace my Linksys, which is also a great brand but the wifi connection just does not seem to be as good.

  2. Great deal on a refurb!

    Posted by Mark Hindle on 4th Aug 2016

    I bought this router a few weeks ago and I am very pleased with it. Though this unit is refurbished it arrived in very good shape. I had never ordered from this company before but I definitely will again.
