I order this product to replace my outdated Comcast modem . I order it on a Friday and receive it on Tuesday with free shipping . packaging be sufficient and product arrive intact . install be easy -lrb- except work with Comcast - Make sure you have you Account Number and Phone Number for the account before disconnect you old modem -rrb- . I have about a 25 % increase in speed , base upon internet speed test . would highly recommend purchase this modem .
