It works well for me because I put in a default of 2/3 pot on all streets, then on FT, my mouse wheel adjusts the bet up/down in SB increments. Playing a lot of tables, I never have to click the bet box and type in a number. Add in my left hand resting on F1 (check/fold)/F2 (call)/F3 (bet/raise), and I almost never have to move my hands or look at my keyboard. More time for decisions.
