We started with a set of Sefac's, talk about wasted metal those made better jack stands than they did lifts. We got about 6 months out of our Koni's before they decided to make life interesting. I really get tired of playing ring around the rosie with that damn key getting them to link up only to get an error code. The Rotary's don't use the key they will recognize them selves, plus they have pockets on them to move them with a forklift. With a 20,000sqft shop that makes for a great feature.![]()
