JoyStone 42 Hole Automatic Bubble Machine vs Gazillion Bubbles Tornado Bubble Machine

The Tornado is the stronger pick for most families: it pushes out about 4,500 bubbles a minute, runs for hours on four AA batteries, and owners consistently call it easy to use. The JoyStone counters with a fully enclosed body that resists leaks and a bottled-solution feed, but its 3.9-out-of-5 rating from 174 buyers is middling. Build on both is basic plastic; the Tornado's sealed battery compartment and included solution make it the safer bet for outdoor play with young kids.

• Choose the JoyStone 42 Hole Automatic Bubble Machine if you want a leak-resistant enclosed design and prefer feeding it from standard bottled solution.
• Choose the Tornado Bubble Machine if you want maximum bubble output, long battery-powered run times and a machine that comes ready with solution.
