As far as I know the clones have proven much more reliable. I've only heard of one clone auto firing. If the majority of fails were counterfeits, we all would know it.That's total bull, most or all of the button and auto-firing issues have been with the authentics and they know it (including my authentic with a very mushy button after a few months)... At least if they'd own up to it and promise to resolve it, it would give customers peace of mind.
If I wanted another istick, I would probably intentionally buy a clone from FT over an authentic.
