    "Love !...Fast !...Being able to use the higher gigabit ethernet ports allows me to maintain higher speeds that my cable provider offers....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 "

    "Love it...Not bad...Best Modem for sub gigabit connections...There usually isn't a lot of need for buying a Cable Modem with Spectrum because they don't charge a monthly rental fee for them, but this fixed a problem for me and it is a very robust cable modem for mid-tier speeds."

    "LOVE IT...Good buy...More advanced Gigabit modems were not able to stay connected 24x7x365, this one in up-and-running with no issues....When I went to buy the cable modem I selected based on ratings and price, the Best Buy salesman recommended this one instead because it "plays well" with the Wave service I have here in western WA."

    "I love...Great ....I love that it takes up very little space, but due to not having external antennas, it goes out a lot if being used for wifi access for smartphones, but is fine with being used for laptops and computers if you don't mind a few delays and even though it's a dual- band wireless-n router with built in cable modem, it's difficult to get the secondary band to function and wouldn't recommend it for large homes but it's rather more suitable for apts....Turned out it WASN'T the problem... I decided to keep this unit because I like how small it was and how well it works (now that Comcast finally ran a new line to my place!) Good value, works great with multiple devices using WIFI."

    "Love It...It's ok...I grabbed this modem on a whim as I already had a cable modem running well yet it was a few years old (Surfboard with 8x4 DOCSIS 3.0)....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."
