At last year's Harrisburg RV Show, they were one of the big "improvements" that a number of mfgrs were bragging that they now used... Knock on wood - No problems so far with my 3 Schwintek's... I make sure that I hold the button for an extra couple of seconds when extending or retracting, and I NEVER stop mid-extend or mid-retract.... From my readings, these steps seem to be key.
