My experience was expensive, when I lived in an apartment while going to college, I bought them and one leaked and covered the carpet, I had them in a cardboard box, my fault, but they can leak. I had some expand and they don't stand up very well and can fall over at the most inopportune times. For what it's worth, it's not worth it in my mind.

The other storage system I've heard about was a man who used brown glass jugs and filled them with marbles until a couple of them got heavy and broke.
