I already had enough problems with places with too many wifi networks working on 2.5GHz channels, this router solves the problem supporting 5GHz.
I use it everyday in my apartment without having wifi problems and I am going to bring it with me every time I travel.
I am very happy with portable TP-Link routers, I have the WR703N, MR3020 and this one.
So far this is the best one! Same size as MR3020 but bigger than WR703N.
