Since it clearly says not to use the bar as a lever, there is no way to use the wheels to move the very heavy base. I basically smash my fingers trying to lift it, then drag it around. On top of that, the pole is smaller than my umbrella, so it doesn't even fit. If I could figure out how to move the base, I would just buy a new umbrella, but this is ridiculous! Why have wheels if you can't use them?  

Pros: heavy enough
Cons: no realistic way to use wheels to move it
