Hey looked at the ad you preload the nine shots and then press a button a time, or two, or three to refill. Head to the patio and never go back to the bar. Might have to get one perfect for the pool or beach. I guess though you still need ice and gonna have to get up to go pee...hmm have to think about it??Simply put, that looks great, for the first drink. After that it is clearly to complex and way to many parts for me! Love the idea but could not fathom doing that half way thru the evening!
