Query: this saves my back

I don't know how people can go to the beach w/o wheeled carts. I have so much crap, beach chairs, food, towels, drinks, bags, life vests for the dogs, etc. I fill this to the top and wheel it down and through the sand with no problem. This thing has taken wear and tear with no problem and it's been a year. One of the hinges does stick, though, when it's time to fold it up. I think it's due to sand being stuck, so it probably could not have been avoided.As far as quality, I do believe this is better than many others...I saw a Tommy Bahamas one at Costco and it was visibly of inferior quality.
