The ACHILLES has, in this case, its strongest point in the "heel" of the vibrator. The robust execution of the clitoral stimulator will make you gasp for air when you reach the big "O"! Made of high-grade silicone and ABS, the ACHILLES comes with two 10-speed motors rev up to a mind-blowing 7000 rpm, but stays very silent (> 50db) at the same time! The ACHILLES stands 21 cm tall and has a girth of 3.5 cm.
