The Bubble Max X2 allows you to choose either low or high bubble production by having either one or two wands going. You can continuously produce bubbles for days, weeks or months without the labor of having to fill every few hours when you choose the Auto-fill version. The X2 is also available as a system, which includes a fan and stand.
