Very easy to store. I have them up against my wall at a very slight angle and since they are kind of heavy, the weight keeps them pretty much planted against the wall. Hands down one of the best investments I've made since I like to do the work on my own cars. Plus once the car is lifted in the air, you have PLENTY of space the work underneath...a good 20+ inches of ground clearance. This Youtube video has a good review and shows how he stores it up against the wall like I do:

 

I too have the quick jack and for the GS F you REALLY need to get the EXT model. The standard quick jack will barely work with the shorter RC F. It's an okay product. Poor quality control and should honestly be half the price, but it does make working on replacing brakes or swapping tries a much more pleasant job than using a floor jack and stands.
