I was skeptical when ordering this product.  I had never before heard of TP-Link.  Because this router is available for less than $70, I had real reservations on just how well it would do in a real working environment.I was pleasantly surprised to find out from a performance standpoint, there was not much difference from the "big names."  After EASY set-up, I began using the router in my small insurance agency.  I didn't tell my Office Manager I had changed routers.  I waited for her reaction.  She never even noticed the difference between the TP-Link N600 and our previous Netgear WNDR4500 which, incidentally, was double the price.The wireless performance of the N600 router turned out to be a pleasant surprise. Even though the router is less than half the cost of some of the "big name" routers, there is no lacking of performance whatsoever.  You may not like the look of a router with its external antennas, but there is no doubt the router utilizes the design effectively.  The speed is outstanding and the range is exceptional.All in all, TP-Link N600 comes equipped with ALMOST every major function you could want from a router.  It is MISSING a 'Guest Network' feature which allows you to have separate security and access restrictions for guests accessing your network.  Other than that, I believe this router can certainly compete with the "big names."Adding to my satisfaction, the TP-Link N600 comes complete with a 2-year limited warranty.The TP-Link N600 is a very impressive dual-band router that performs like the "big names" but costs about half the price.  It doesn't have the most attractive interface, but it isn't lacking many features.  Those looking for a best buy for the money, the TP-Link N600 is really hard to beat.
