For twice what the tool costs, you can get the thumbscrews which I absolutely love. They are exact replacements for stock (1.5 turns = 1.5 turns) and extremely easy to use. I spent the first month I had them making 1/4 turn adjustments until I found the bike's sweet spot. You also can see exactly how much you're turning and where they are at all times.
They are scored at halves. When all the way in both mine had one of the marks exactly facing the right side of the bike. I used a sharpie to make a black mark on each scoring facing that side. The black mark is now one turn, the other mark is 1/2. Really cool.
