    "It's ok...Love it....Great speed and reliability...As far as the modem itself goes it works fantastic and if this review was just on the equipment it'd be a 5 star review, however since this asks for OVERALL rating I have to take into account other factors such as support and I must say without a shadow of a doubt that Netgear support is the absolute worst."

    "i love...Love !...This modem is great for time warner customers (now spectrum ) also because I have my own wireless router not only am I saving 10$ monthly rental fee for the modem twc spectrum provides but im saving an additional 4.99 fee for wireless because I am using my own wireless router and this modem does not have built in wifi, This pays for itself my internet bill went from 50.00$ a month to 34.99 a month , and I am getting faster service and speed compared to twc spectrums modems , this is a must have ...You can expect this to put out up to 150mbps - if you have a higher internet speed from your provider it would be worth getting a more expensive model that can handle faster speeds, as you'll never actually get speeds as fast as it says on the box."

    "It's ok...Love it...This is the perfect modem for anybody was a high-speed ISP provider such as Comcast I am I currently have Comcast and I am able to push almost 350 mix down as well as 30 to almost 35 megs up but dad is currently with my 250 extreme package so with this modem I am almost adding an additional hundred megs just with the modem all alone but I also highly recommend that you also grab a router that supports this high-speed modem...I bought this Modem as I have been in the business for over 18 year... I have never had to buy a modem before as I was the guy that would test all the new modems as they were released to the MSO's... I moved and no longer in that role so I had to buy one."

    "I love...Good ....Price - for the combination of what you are getting in Router and modem capabilities coupled with saving the high monthly rental fee I think this item offers a very good value Overall this has proved to be a great two-in-one solution as both a cable modem and router with the added benefit of saving me from a monthly charge for lesser equipment....We have multiple devices using this modem and a smart TV hooked up to it as well as having my wife work from home somedays and we rarely experience a slow down, and if we do I think it is related to the Comcast service not this modem."
