To learn the correct twist, put the large loop around your wrist and then twist in, squeezing your wrist a bit. Then feel how you can build up the pressure while turning. Can be left or right.
First practice on the wrist, and then you know the movement with which you can open a lid.
With the Twistyopener alone, you spin counterclockwise. With the combination of Twistyopener and Twistyholder you turn (with one or two hands) the jar or bottle clockwise.
The Twistyopener holder as a 'third hand': your hands can now turn in the same direction together. Or as a 'second hand': one hand can now open the cap or lid.
