Those things are so expensive at the Parks! They perform fabulously when the reps at the carts are using them but every single one we had stopped working the next day. We tried cleaning them out and all sorts of other fixes to no avail. They’d work for a few more mins in lackluster fashion then quit. Sad kids but no way I’d pay to buy replacements.
And yes I love bubbles…we have a bubble machine that we use on the balcony at the resort where they float up into the night sky without offending anyone hopefully.
