I have ordered, reviewed, tested, and created content with many bubble machines on the market. This portable, C-charging 360°, rotating, 2-speed, bubble machine is worth every penny!!! This bubble machine isn't just made for kids, but for anyone who is a fan of bubbles and kid at heart. With the built in handle, you can carry, hang, even hold the machine during the easy clean up process. Easily stores, takes up minimum space, and allows 4 hours of use when filled with extra thick long lasting bubble solution. I even have a great photo I could share of my machine hanging on a garden shepherd hook in front of my porch magically filling up the neighborhood with big, bright, long lasting bubbles. I give this product 5-stars ????? because of how much fun I've had with this machine!!!
