I have be use this splitter\/amplifier for over a year now . I have two 50 + foot cable run located in different room of we house - one to my hdtv cable box , the other to a cable modem . I can surf through the cable OnDemand catalog , stream show and do network intensive activity -lrb- downloads\/uploads , voip -rrb- simultaneously without a problem . bi-directional performance and the overall connection have be be rock solid . in the past , I have use both electroline and pct splitter\/amplifiers . we have fairly unstable power where I live , with frequent short outage and spike . for both the electroline and pct product , even though they be always plug into surge suppressor -lrb- both the electrical and cable line -rrb- , they eventually blow out . the Motorola have weather a year 's worth of storm and random outages\/spikes and be still run great . do not know if this be just luck or a sign of the high build quality of the device . the connector be solid -lrb- nothing even come close to wiggle -rrb- and the overall build quality appear to be quite high . I have not have to touch it since I install it , so I be a happy camper .
