Like i said i would do....i received a resolution to my issues as of 4/27/15. I wont delete my thread but i agreed to edit it and add that i got a resolution to what was said below.Okie dokie.....where to start where to start.....i guess let me add a disclaimer to this thread so it makes a bit more sense:
I am in no way saying Bitmains products dont work.....because they do.....this thread is for the lies and dodging they have been doing to me and many other customers for a very long time which not only wastes our time but has cost us quite a bit of money im sure....i know it has cost me money and time that is worth more money so enough is enough its time to post it here for everyone to see even bitmain.now that i got that outta the way lets move on to the issues im having. like many when the s5 was first announced i waited and waited for them to be released but when they were i was asleep so i missed the first batch. luckily though they released batched 2 and i was able to pick up 3 of them. the total here was $1239 bucks as seen in the pic below of my order receipt. I paid on time and was happy with the specs posted by them and awaited their arrival.
when they came everything seemed fine but when i tried testing the features they listed on their advert all over the place i wasnt able to get the results they said would happen. by features i mean:
1. Quiet mining (they sounded like a jet taking off non stop! theres nothing quiet about them!
2. can run using 9v power to lower power consumption all the way down to .2w per gh/s
i figured it had to be enabled via a firmware update or something and i had time before they werent worth mining with anyway so i waited to see what kind of tested was done by other users. well after not seeing anything for months i decided to email bitmain to see exactly what psu was used to run these at 9v so i could eliminate any hardware issues because i paid for these s5's because they were supposed to go down to .2w per gh/s which would increase their usability when the diff goes up and they cost too much to run. what i got back from bitmain was kinda suprising:

Hey
Is there gonna be a firmware update that lets the antminer s5's support the voltage inputs u said they are supposed to handle?? Because right now they cant run at 9v or 10v without wigging out on us. The 9v supply is more then enough amperage as well and same goes for the 10v supply but they either throw up errors or run then stop randomly with x's leading me to believe its a firmware issue and nothing has been posted about any updates to the firmware so im getting a bit worried now lol. Also do u have ne ideas on reease dates for new miners?? They dont have to be exact dates...generalized ones like for example "april 15-25th" or something like that work just fine. I just wanna know so i gather up some more btc to bulk order when the batch get released. I was going to order the s5 but i saw they sold out so now i wait for the next model which i can only assume is the s6."
"
Hi,
for S5, Input voltage should not be less than 12.00V, since it is based on serial power solution and there is no DC/DC inside the miner. Higher input voltage will cause higher mining efficiency.
And it cannot work well with 9V or 10V.
Best Regards
BITMAIN"
so right there i saw 2 issues. one of which was confirmed by someone that actually knows what hes doing it seems and he said at higher voltage the opposite happens....so why support would say add more voltage is a bit weird but the main thing is that the states the s5's dont run on 9v power....but like you saw above thats how it was advertised. it wasnt advertised as maybe it works or that it wasnt tested....the ad clearly shows that past batch 3 (i think it was there in batch 4 as well....the ss is from the batch 3 advert because its all i had available before the revissions) that if you want to run it more efficiently then use 9v power but when using 9v the controller wont even boot up and if it does boot the boards arent detected....no psus will work and i have tried multiple so the feature that drew me and others in to buy miners was a bold faced untested lie! when i continued on with asking what they meant about 9v not working this is what i got:
"
sHi,
Sorry for the inconvenience.
After double checking, we confirm the S5 cannot work well with 9V, so we crossed out this description."
"
Ya but what happens now to the people that paid when that feature was available??
Sent from my iPhone"
"
Hi,
We have correct it immediate after we get the info, it has been a long time now.
Once the miner can work well with 12V, no need to worry about it.
Thanks."
"
Hi,
We published the miner with 12V,1155Gh/s hash rate guaranteed.
We only mentioned you may use 9V, but we didn't promise the hash rate under 9V. As you can imagine as well, even if you can connect the 9V to the miner, the hash rate cannot be 1155gh/s as well since you didn't provide enough power:)"
after checking further i noticed no announcement or compensation being given to buyers from 4 batches prior to this silent "change" were given. its sickening that a company like bitmain chose to do this to buyers and i have been trying to get compensation since this issue was mentioned but they have stopped replying to my emails about it all together and the support here tells me to email bitmain itself which obviously doesnt help since they r ignoring me alltogether.
If this werent enough i had anout batch come in that was ordered because the specs were revised and didnt mind the miners themselves except the noise the main issue is the company and their huge ass lying schemes to steal customers money and silent revissions well my second batch was nothing like the first!
i paid $1700 for 5 "Brand new" s5's and what came were 5 dirty and used miners. the first 3 that came were clean and fresh which when comparing the 2 im left assuming a few things and im pretty sure they r correct:
1. the miners sent when first released are basically brand new....not much use on them at all which explains why the first 3 i ordered had zero dust as far as i could tell.
2. batches after the first couple of batches are used and abused miners that are nothing like the first batches...they have been running on shelves for months up to that point so they r caked with dirt and dust.
3. by the end of their run they start sending miners that are dirty used and have had repairs done to them which these miners have had repairs done. solder paste does not leave residue un the form of globs of flux. solder paste if lobbed onto the board will leave blobs of solder which none are to be found....there is so little flux in solvder paste that ot leaves little to none behind. my boards have globs of crusty flux on resistors in specific places and the boards that do also have the letter R written on them with a black magic marker...not by me but by them! they also have other wirting on the boards that is also caked over with dust so these are NOT new!!!!!
Bitmain sells NEWWWWWW miners but sends used and overclocked miners?? the miners i got had warped side panels. when taking my heat gun over them a foot above i noticed something.....when trying to flatten them out and they get hit with warm air the first thing they do is curl a little bit. after a little bit longer then flatten out to how they should sit. this was interesting to me because thats also proof they have been run and run hard! the miners i got the first time were straight but this batch of 5 were warped and bubbled like they were subject to more heat they they should be subject to.
i also noticed on some components there is thermal paste. these components are on the oposite side of the heatsink side so no thermal paste should be there. the paste isnt on just any components either its in the rows of black components (not the asics) that line up with screw holes that arent used when they come to the consumers end which leads me to believe there was another heatsink attached to the oposite side of the board but for what?? well when coupled with the above info im left thinking these were run overclocked for quite some time and died....they they got repaired amd resold as "new" but werent even cleaned first. i ran my finger from top to bottom and it was pitch black! it was so grimey i cant even describe it right! when i emailed them they replied with:
"
Hi,
What's the order id? May you provide some graphic as reference?
all miners are new, because the factory is under construction so it will be lots of dust when doing aging test for several hours。
sorry for the inconvenience.
And please confirm whether the miners are working well now."
i replied saying that this amount of dust isnt from a few hours of running. no place in the world gets this much dust from only a few hours! its rediculous.....but then it gets even better:
"
Hi,
Very sorry for the inconvenience.
May you turn on the miner can confirm whether it can work well? Provide us the screenshot of Miner status as reference.
S5 hasn't been sold for long time and there is no used ones. due to factory is still under construction, there is a lot of dust.
Sorry for the troubles."
so basically if the miners work y r u complaining?? well im pissed because i had to clean this shit off these "brand new" miners and they i get dick slapped in the face by an excuse that has been used for years now.......they have been saying this factory is under construction since the s1 days.....and even then if this is from a few hours of them running y is not every asian in that place dead?? the buildup in their lungs from a single days work should kill them if this was true but hey none are dead so what does that tell ya?? they also have the nerve to imply working miners r worth the same used and new?? so will u buy my used g35x and pay me the $50 grand it cost brand new?? i highly doubt i can get away with that one and i bet the first thing they would say is "but its used" and once i say "but turn it on and make sure it drives" they will just walk away so y do they think its ne different with every other product sold anywhere?? no one should pay new prices for used equipment and no one should get sold something based on untested lies and then get ignored when they want compensation for their fuckup.
resolutions i will accept:
1. full/partial refund for miners bought based on ur lies so basically 8 s5's
2. new miners for free (not 8 new miners im not greedy and unreasonable) to offset the shit u dropped on me 2 times in a row!
3. everyone with an s5 order before batch 4 gets a patial refund for your lies.....every batch of s5's gets a partial refund for the non quiet feature that is clearly also a lie!
