Space Bag for Luggages?

Question

I have seen that Space Bag is now available for Luggages for travel, but one thing that i am concerned about is that what if they (secuirty) makes me open the space bag? i would just put clothes anyways, nothing else.

Answer 1

Don't bother.  I bought space bags, filled them up, followed the directions, and put them under the bed.  

They suck!!  Air crept in and they expanded.

If that happens while they are in your suitcase, your suitcase is going to pop open.  

Also, airlines have weight restrictions on luggage.  I always manage to go over a few pounds even without space bags.

And you have to pay extra for every pound over!
