IMO this is a great deal if you want an AC router for speed!
Saving around £60 vs. amazon.co.uk!
Remember this does not have a built in modem. You will need a separate modem (e.g. Virgin Superhub for cable/ADSL modem for ADSL/FTTC modem for FTTC).
Most providers supply a unit which can act in modem only mode allowing this router to take over all other functions.
