I bought this bubble machine for my sons 3rd birthday party!!! It was soooooooo much fun with A Gazillion Colorful Bubbles EVERYWHERE!!! I didn't have Any problems with the machine leaking. I set the machine on a tv tray and up in the air the bubbles flew... Just for the record they also fly up even with the machine on the ground. It's Super Easy to use and Tons of fun for kids and adults. I do recommend buying the 64oz refill bottle. The 8oz bottle that comes with it lasted for aprox 15-20 minutes blowing non stop. Overall a Super great product that really produces a GAZILLION bubbles.
