Bitmain, you promised this 7 weeks ago.......

Since then you have released two firmware releases both containing the older, security vulnerable cgminer versions.......as well as using it in these S4's.........

I have S2's that I can't get spares for, despite you having 100's of them hashing away in your premises. I was told to wait for the upgrade kits by you in an email, only to be told the very next day that you won't be doing them anymore, so instead you offer a $200 coupon that runs out in 4 days for a vastly overpriced miner that has untested firmware & the same security issues in it as all your other miners have......what on earth are you thinking?

Too many broken promises Bitmain, resulting in me having miners that are unusable due to lack of spares, and even the ones that are working aren't safe from exploitation. There is absolutely no way I will buy an S4 in it's current state at that price, meaning I've also lost the $200 dollar coupons you issued as a "we're sorry" gesture.

You seriously need to sort your business out - I'm completely sick & tired of hearing the same thing over & over again but nothing being done.

Your reputation is on the line here Bitmain, I suggest you start treating your customers like customers, not as some kind of never ending money supply!!
