Jack Stand Safety: Kwick Lifts

I am curious to hear opinions, both pro and con, on this type of lift.  Some folks use them as an alternative to a 2 or 4 post lift, especially in a garage with limited space or height.  Do you own one of these?  Like it?  Hate it?  Please feel free to comment.

Here is a pic of how the rear of the Kwick-lift is raised.

The owner of the Corvette above commented:

 "One bridge (that's the part that is attached between the two ramps) is standard with the Kwik Lift, a second bridge is optional. I also opted for a second bridge. The bridge permits the use of a bottle jack to do exactly as I have done to lift the car and install jack stands. The bridge(s) slides back and forth and has a hole on each end to permit bolting it in place on the ramps. Thus the bridge can be positioned anywhere along the ramps as desired. Also, the ramps are telescopic and have 3 sets of bolt holes to secure the sections together once they are extended to the desired length. I have mine set at the shortest length".
