They skipped the bit where the whole spring/compressor starts to rotate once you have generated some slack (but not enought to get it out). Although that's more of a problem on the rears where they are recessed into the bottom arm.
Other than only having one bolt to undo/do up instead of two that looks no easier than using my trusty old universal compressors, i thought there was gonna be some sort of super tool there that whips em in and out in seconds.
