1.4 Gbps Arris 32x8 DOCSIS 3.0 modem purchased recently from Bestbuy for 109+ tax. It was only used for about a month, then I find out that Spectrum provides a modem, where Charter had me purchase my own in the past. Thus I received a free modem from Spectrum I am using.
Thus my loss is your gain, too late to return. Asking less than half price of the brand new one. $30 and I guarantee to be in brand new perfect working condition or your money back. It is still under warranty.
