Looks new. Showing expected up/downlink speed. The only problem I had is a trolling ISP on the phone.

I bought this modem because my ISP claimed my existing modem was defective. But the problem turned out to be in their wiring. Never trust your ISP, especially if the support is outsourced to people you can barely understand. Suddenlink, (now calling itself Optimum) is by far the worst telecommunications provider I’ve ever worked with in over 30+ years. I've dealt with everything from giant conglomerates to tiny mom-and-pop telcos, and Optimum wins the award for absolute worst–by far. This is a quality modem, but just because it’s 32x8 won’t make it run faster than a 16x4. Using more frequencies doesn’t give a better connection or improved reliability. So I went back to using my old reliable 16x4 version of this modem. I did add fans for either side to help it run cooler, though. (see photo) You shouldn't believe reports that claim modems last only a few years – that’s nonsense. Take good care of it, and it should last a long time. By that I mean, keep it cool! Most electronic equipment has insufficient cooling, imo. But add a little fan or two, and it will keep going and going. (I bought my fans on Amazon, of course!!) I own many “refurbished“ modems, routers, and even computers. Over the years, I’ve saved a bundle doing that, and never regretted it. For most electronics, if it works well for 30 days, it will likely keep working for years. Buying directly from Amazon, I know I’ll get my money back if anything goes wrong during those first 30 days. The 16x4 version of this modem is no longer available, so I highly recommend this 32x8 one. I’ve had no problem getting over 500Mbps with 16x4, so this one should work great, too. If you’re considering getting a DOCSYS 3.1 instead of 3.0, first make sure your ISP fully supports it. You could be paying extra money for nothing. My ISP claims 3.1 compatibility, but that’s just marketing hype. Years ago, they announced they would never support 3.1 features. If your ISP doesn’t *guarantee* to *fully* support all 3.1 features, you can confidently assume they don’t, and probably never will. Replacing their equipment to be fully compatible with DOCSYS 3.1 costs a lot of money, but marketing hype is free. Love Amazon!!!

Brand is the industry std. Used to be motorola . This device is now considers old and may have fallen off Cable providor's list .. Max speed .. is enough.. 200Mbit or so.. Providors starter plans will be fine. WILL not do 400Mb for sure.. YMMV ... check cable data providor .. THEY LAST FOR EVER. Back to basics.. NOBODY NEEDS BIG internet speeds.. it's all marketing . .Your game wont go faster.. This will easilly handle 2x HD TV streams ./. DVD is 12Mb and Blu-ray MAX Out 48 Mbit. Neither ran MAX

I really like the reliability of this modem. It works well with my internet provider and was easy to set up. No more monthly equipment rental fees.

I decided to upgrade my internet but the old modem was too slow. I'm always wary of renewed products but this met my needs and at 25 bucks on sale I couldn't resist. I'm glad I made the purchase. The unit looks new and works fine. I paired it with a 35 dollar Opal wifi router and it makes for a nice little setup.

The ARRIS SB6190 worked well with xfinity internet in the end. Had to have a technical call with xfinity, where I told xfinity the modem mac number and they registered the modem on their end manually. The xfinity app adding-your-own-router option just doesn't work no matter how many times I try. I had brief issue that xfinity redirects Google check internet status requests to its own internet page as if I didn't pay for the internet service, making my Android based TV thinking the internet is not working. That issue was solved by having a chat with the chat bot to reset something on their end and the modem on my end. The chat bot is not smart but does get things done like resetting something technically or get a tech support to call you. The modem supports my internet package of 200Mb download and 10Mb upload nicely. Make sure your ethernet cable is well connected, otherwise you may stuck at 100Mb mode like I did at first, which resulting maximum 90Mb download when I run any speed test tool, glad it not the issue with the modem but just my cable connection, any legit CAT 5e cable would work well. PS: I am switching from a NETGEAR C6300BD, which has a issue that it will get stuck when the power flicker for a second, resulting loosing internet unless manually unplug and plugin the power to the modem. That issue causes serious accessibility issue as nowadays even my garage needs wifi to operate.
