Interesting idea but way overpriced for the amount I'd use it.
The wheel's too big. The higher the load, the more work it is to keep it upright. It's mainly a wheelbarrow with a 16" wheel. A wheelbarrow with a 12" wheel will be a lot easier to control. The handlebars on the Packwheel are at about the same height as the top of the wheel so you have no leverage to keep it upright. You have to muscle it.
