I bought the product from the store and unfortunately the charger with the cable that comes with it does not make good contact (resulting in it not working at all). I found my own cable and it worked... Besides that, it didn't produce any smoke for no reason. Simply put, the product is faulty, of course it's not the store's fault...

The effect it creates is quite impressive. It reminds me a bit of a fountain with colorful lights and fog, or a witch's cauldron boiling a magical potion. The steam that comes out and creates the fog effect is cold. As for the negatives, the way the fountain throws water around causes everything around it to get wet, and precisely because it requires a limited amount of water, you will need to refill it periodically. Unfortunately, the photo cannot show the amount of steam it creates, which is perfect for household use!
