Not advisable to buy
I was excited to use it after I receive it. But I was disappointed using it. It never stayed on the nipple and you need to put it every minute. A big disappointment, instead of using it hands free, you need to put it every once in a while. It has no tingling effect, like the one described with its brush inside the cup. OVERALL, a big disappointment... not worth a penny. :(
