Works, but at a cost
Customer Rating: 
I've had this for a few months; with the exception of my TiVo box not being able to "call home" it has worked.
As noted by some "1 star" reviewers, it does slow the rest of the network down. I've not seen 3 meg to 400K changes; but it is slower, which i would expect for something altering the QoS of packets on the fly w/o knowing "what's next".
I solved the tivo problem by adding another wifi adpater in front of the network optimizer, and the only thing connected to it is the tivo.
When I'm on a call; the network crawls; and sometimes when I have a LOT of downloads going (10+) it also seems slower; but it's a trade off -- is the phone call more important, or is downloading? You cannot dynamically 'switch it on' when a voip call comes in or you make oen -- it's just on.
And there's no adjustments you can make to re-prioritze packets.
it works; and it makes voip calls very usable for me (before, i rarey made them except when someone else was on the landline).
I've noticed that "the longer it's up" the better the overall performance is -- if we have a power outtage, I notice network traffic is bad when it 1st comes back; then seems to "even out" -- I don't know if the optimizer is doing some "learning" or not -- but it's a side effect I've noticed.
With everthing in life, there's tradeoffs -- you just have to decide what's more important. overall, I think it works as advertised and network performance doesn't suffer as much as some claim.
