saw the reaction of the members of this forum and people who have experience in the mining, regarding this new product S4 + .. it is a great disappointment for most part of them !!
for me this new product only slows the progress of Bitcoin and minors .. UNFORTUNATELY
You are missing a huge jump for Bitmain. They went to the 220/240. This is HUGE as far as future designs.
If they don't lock all miners to the 110/120 it opens the door to much bigger miners.
