I acquired this for my dog food and treats.  It's the perfect size to fit the 30+lb. dog food, which is a huge life saver!  Nothing is worse than having an air tight container that only 80% of your dog food fits in and the other sits in a rolled up bag getting stale. The scoop is nice and sturdy.  The wheels look a little flimsy in pictures, but I was pleasantly surprised how nice they are in person.
I am giving this 4 stars because the smaller container doesn't have a secure connection to the larger.  It's a small groove/foot that lines up, except the lid is a little warped and the groove isn't that deep so it kind of sits atop.  It's a great and durable set.  I would highly recommend, especially if you plan to put the smaller container elsewhere.
