After I received the product and loaded up 4 alkaline batteries to get it roaring for the first time, it was a pretty good experience with the disposable cup. Second time it was not as good because suction was noticeably weaker. I thought it was a fluke so I ordered a reusable cup. When I got it I noticed the batteries were dead. I began to wonder about the products cost vs value as this was the second time I had to replace the batteries in 3 uses. After a couple more uses of the reusable cup, the batteries died again. I would advise anyone purchasing this controller to invest in rechargeable batteries to get your money’s worth. (That is what the company told me when I wrote in to complain).To me, it’s not worth it. I’ll find other less expensive means to enhance the experience. Mostly my old faithfuls 😊
