Hello and thank you for your honest feedback.
I am sorry you are having issues with this spinner. A Hammer is generally suggested but you can also push the wheel down against the lock nut on the floor to secure it in place. As for the wheels, generally they will spin in whatever direction the wind blows, and should not matter which direction the wind blows (but this does not mean they will necessarily all turn in the same direction, depending on the angle the spinner is facing into the wind).
If you need assistance with assembly or any parts please let us know. Otherwise if you need all the wheels to spin in one direction they are not designed like that but I can see if there are any wheels that may be.
