Agreed. If anybody's experiencing this issue, they should start with the easiest solution first. Sometimes it is just dirt. But the manufacturing flaw is still present so that's why you should look into replacing it if cleaning it doesn't work.
For me it DID take some time cleaning it, I had to be fairly thorough: not just 20-30 seconds, but about 5-10 minutes. But I have had no issues since.
There is definitely some kind of flaw, the sticks shouldn't behave this way from dirt. The point I am trying to make is that it's easily fixable for about the equivalent of 0.05 USD.
I describe myself as a little dose of toxic masculinity.
