Perhaps some production problems and out of spec lose parts are the cause of that 1/4 good ones
But they can't just say sorry all of these sticks are bad because if they do they can't keep selling them
I order 4 from amazon, because why not. I will receive them today, maybe they will be fine, there is no risk rlly, worst case i will send them back, the best case good no clicking sticks, middle solution free a bit faulty sticks i mean why not.
Edit: This is funny i just received them and from just feel and sound/click test 1 of 4 seems to be click free : o 3 of them have some click when sliding opossite to the ribbon and one has some scratchy unpleasant feeling and sound when turning around
So indeed 3/4
