As silly as it seems... it works.  Airbags are very useful.  I used to be on an aircraft crash recovery team and we used a much nicer version but nonetheless they do work.  The only real downside is you should use something flat so that you don't puncture them.... i.e. sheet of plywood

yep,i ued to have to of them,they are some of the best jacks around,until your little compressor goes to sh!t

I've seen a similar exhaust bag, it did not lift the vehicle "in seconds".  Minutes, yes.  Actually does work!  Better than the baby jack in the back door unless you are on a hard fairly level surface.

I think I'm going to buy that. BTW, there are air compressed kacks(like a control version of an airbag that my freind uses that literally inflates in seconds. Which would be better?

here is another one that looks pretty good but more money
