Switch problems - Streamlight PT Professional Tactical Series 2AA LED Flashlight

This is my 3rd streamlight of various types, one works flawlessly for 3 years. But it's only function is to turn on/off, no modes.
The second streamlight will turn on/off reliably but not cycle modes.
THIS ONE DOES NOT do either well.
Out of the box the switch will not work correctly, sometimes will turn on, sometimes not. It will never cycle through any other modes. Only on/off, when it does work.
Will not buy another streamlight. I'm a flashlight junkie. with more than is needed.
Best I have found are the 4sevens. I own 15-16 of these and EVERYONE WORKS PERFECTLY. I have them on every keychain, in every glove box, in every bug out bag, in range bag, in med kits...etc (and no, I have no affiliation).
The second best (IMO) is Fenix. I have 10-12 of these. ALL WORK PERFECTLY. I have many others, these are the best.
So, if I can buy that many flashlights from those two companies and not a get a single "bad one," that is remarkable and of vailue to consumers.
I have 10-15 headlamps (bragging now)...but that's another review.

I was curious so googled it...other's are having switch problems as well.

Streamlight...66% defect rate for me. Never Again.
