Based on the limited times I've used this folding wagon, it appears well-constructed and promises to withstand repeated use for construction, personal fishing, gardening, and family outings. The wide, solid tires are appreciated for added stability.
The instructions directed me to install the rear non-caster wheels so that they point TOWARD the center of the wagon. Currently, I have installed them so that they point AWAY from the center. While I may change them around later, I chose the other direction to reduce the thickness of the folded wagon and increase its stability to "stand up" when folded. I have also incorporated buckled straps to hold everything together when it's folded and stowed.
Cons: Can't think of any. While I do not like the use of Velcro (it sticks to %26 catches on to about everything), I understand its uses. It's cheap and lightweight.
I don't intend to subject it to its 165-lb load limit, but I definitely like the margin of safety %26 strength. I was impressed enough to purchase a second wagon!
