My Tower unit wobbles when I push on it. Is this normal?

The good thing is, there is nothing wrong with your unit if you notice the fan wobbles when you move it. This is by design. We build our products with tolerances to allow the unit wobble a little back and forth. This is done so that if the unit is bumped into, it is not rigid to where it falls over. This wobble allows the unit to maintain balance and absorb the impact. This helps to reduce the likelihood that the fan falls over and damages itself, or property.
