the first one by far... but they do not sell them on amazon anymore. i suggest spending a little more and buying a horipad on ebay. the 2nd turbo kills batteries and you need to rubberband down the button you want to turbo, but the horipad can turbo a button without a rubberband because it has more turbo options. plus my horipad has benn using the same batteries for almost a year and i finally had to change them yesterday.
