text: I don’t know if I got a bad batch or what, but so far the 5 out of 5 bags I’ve tried have not stayed compacted. The first two bags Instantly failed (my cat was playing with one, so it’s possible he punctured it), my 3rd attempt seemed like it worked, but I noticed the other day that the bag with blankets (stored under my bed) had expanded to the full size. The 4th bag failed me tragically after one use - I packed it to take on vacation and when I repacked it to take it home, it didn’t work. Someone even had a vacuum cleaner and kept redoing it after thinking they’d duct taped the leak. I had to use some serious jenga packing moves to make everything fit in my car. And the hand pump is completely useless. I’ve never used the ginormous size before, so maybe it’s just not possible at this size?... bummer.
