Dee,
Mine was painfully slow also, but I realized that it was a problem with the plastic chain binding around the curves of the track, and not a week motor. I could never make it work better. I finally took the plastic chain out of the track and disengaged the motor, effectively making it a manual curtain (oh, the shame!). It does close as fast as I can move my hand now, but I will admit, I live in constant fear of another Beaver owner seeing my low budget solution. To make up for feelings of front curtain inadequecies, my wife will sometimes make an electric motor sound while I close and open the curtain. It's the little things.
