Query: FALSE ADVERTISEMENT! DO NOT BUY!

These ab slings are DIFFERENT than pictured!They DO NOT have a vinyl covering as pictured AND listed.I had slings like that and they started smelling pretty fast.Amazon should really do a better job checking the products before they send them.What a waste of time and effort. Now I need waste time shipping it back.
