the product arrive intact . setup be easy . just need to plug in the cable , call Comcast , and the whole thing start to work . I have be use the modem for 2 month . so far , there have not be any problem . the price at $ 140 be certainly a bit steep . I have not do any deep technical datum gathering yet . simple internet speed test indicate the modem can certainly support the specific speed I order via Comcast . the only drawback be Motorola do not offer any warranty on the device . so beware about this fact before make you purchase .
