Pros: As an update to my review posted several months back, the USG20W guy just keeps on trucking, consistently and reliably. Deployed in a home office environment for a client, a small business which really doesn't have the time or the first-hand knowledge to be troubleshooting their networking gear. They just need something that simply works and works well -- and that's exactly what you get with a USG -- provided, of course, that you've updated to a new enough firmware version. This particular unit has been working well on version 3.00(BDR.2)C0 for quite some time now. The only thing that seems to bring it down are occasional power surges, which plague the electrical circuitry of the old house where it's installed. If it were not for the surges, I would expect to see several hundred-day uptimes from this thing between resets - no joke. It's nice to have a mission-critical option at the ready for clients who demand it, but would prefer not to spend into the high hundreds or low thousands for Cisco, Juniper, etc.
Cons: The sheer magnitude of the interface along with its heavy browser weight is often enough to deter many novices -- myself included at first. It *definitely* takes some time getting used to, regardless of your knowledge level, as a first-time user. Once you get the hang of this thing, though, routine actions and deployments become much faster, if not outright automated (settings export/import, command-line, etc).
Overall Review: Reviewers who knock this thing for being too complex or having poor this or that (much of which is completely mitigated with proper setup) could perhaps gain quite a bit of insight by stepping back and understanding the level of device that they're getting themselves into here. This is *not* a consumer-class product series (at least it doesn't appear to be the goal with the USG series). As such, in the world of networking especially, newbies need not apply, or if they do, they must understand and be ready to invest the time into actually learning networking terminology, proper networking setups and how they are achieved with the USG. Once that is done, I would anticipate many 1-egg and 2-egg reviews would turn into 4 or 5-egg reviews.
