battery operated fun but limited [SEP] i honestly didn t know this i battery operated when i requested this through vine have i known that i will not get it the product is good and is fun to use with my niece when i have them with methe foot spa is easy to operate and makes your little girl feel extra specialthe items that comes with it is cute but the slippers are super thin flimsy and slippery so be very careful if you plan to use them around wet areas tile floorsthis uses a battery and will cost you more than the unit over time if you use the rechargeable kind then you may not be able to use it longer spa time wise overall the product is good and exactly as described
