Hundreds of tests have been done, it is not a product quality issue. To create better bubbles, we use a durable and powerful motor. Please install it on a smooth and flat wall to allow the foam to flow into the tub and prevent your baby from sliding outside. It is recommended to add 10-20ml of shower gel or shampoo each time, stir and dissolve before use. This will provide the best results for use. In order to increase the service life, it is recommended to put the bubble machine in a dry and ventilated place to dry after use. Batteries should not be left in the battery compartment for long periods of time and should be replaced every three weeks.
