Just to really confuse you some Twisties tighten to turn off, look up Titaner AAA
You could hand either style of twisty to any person on the planet and on average 50% of them would operate it correctly first try and the rest should successfully make it on the second try.
I own both styles and managed to operate both successfully, without too much brain strain.
