Query: Broke the 1st time it was used. Total pain all around.

I was so excited to use this product. The concept is wonderful, however, this product sucks. We have a Graco Alpha Omega Elite car seat that would not stay on to save a life. The straps didn't tighten as well as they needed to get a tight enough grasp. I had to constantly stop and readjust because the seat would fall off of the little shelf. I thought I was doing something wrong but after 3 bright and competent adults read the directions and tried it themselves, it was still pretty unstable. That's not all, the wheels popped off while I was wheeling her through the airport and a piece slid away never to be seen again deeming this a complete and total failure.I have found something much cheaper that actually WORKS. Get a little luggage dolly (you know the ones you see airline stewardesses/pilots pulling around) and a couple of bungee chords. BOOM 25 dollar alternative that actually works.
