It's worth noting that the top of the stand retracts all of the way down, which comes to around hip height or so (on me anyway) and you can overlap the feet of the stands when putting it away, so they don't take up much storage space when not used. If you imagine a square where each side is about 40cm and has a height of around 70 or so, then that's how much space it takes up. Not a great deal at all.
I use the stands for squatting, military pressing, in conjunction with the bench for flat, incline and decline benching, as well as seated shoulder pressing. You can also use the spotter stands (the black parts that stick outwards) placed towards the bottom for deadlifts that are not quite on the floor, if you have problems with knees. It's good for height clearance off the ground.
All in all, would recommend. They're quite sturdy, which is what you want/need really. I'm using standard weight plates, so I'm not entirely sure if the stand is appropriate if you're using Olympic barbells and weights, as it might be slightly too thick for the stand.
