I was hopeful this could work for backseat toy storage and water bottle storage, but have been slightly disappointed. I had hoped that it would be a little more rigid when opened, but unless full, it does not hold its shape. Replacing the water bottle in the holders can be hard for little hands to do.
One plus is the tab it comes with on the backside, when shoved in between the seats, is super helpful in keeping the bin in one place on the seat. The tab is meant to velcro around a seatbelt, however works much better wedged in between the seat back and seat.
We still use it after having it for a year. The construction is quality as it still functions as it did new without much noticeable wear and tear.
