I bought this unit from Broadbandbuyer in June to replace the buggy draytek 2960.
Worked like a charm much improved performance than the draytek. However there is a big bug in the firmware that once you start using filtering rules in the firewall limits you to 100mb - minus overheads.
Not an issue if unless you're on virgin for example. Cisco have yet to fix the issue despite it being raised on their forums a year ago. So if you have Virgin cable 120mb look elsewhere or see if there's been a firmware update after july. Only gets three stars due to firmware issue.
