I think it is time someone finally broke the Silence on Bitmain's dickish behavior to consumers.

I have several batches of L3+, S9s and soon to be coming in D3, apart from this, I have many other machines including Avalons and Ebit E9+

Several months ago, I bought some L3+ for the August batch, late august batch, september batch and late september batch.

The first batches came out absolutely fine! the miners were brand new, and everything ran very peachy.

However, my late August batch just came in. And I immediately noticed very peculiar things about it.

1st: The tapes were OLD, like yellowly old.
2nd: The miners appear to have some wear and tear to them, however, there were not dust on them but it appeared they were cleaned off.
3rd and most importantly: I checked the firmware, and there was something really off!

The first few batches that came, came with firmware 1.0.1.3 which was the latest one at the time (and still is I believe)


However, the NEWER September batch came with firmware 1.0.1.1


Not only this. The older August batch were all really good, they are still going strong.

However, the new September batch now has 3 machines with broken Hashboards and 1 that restarts itself every 5 minutes or so.

So I have to conclude that Bitmain either

1. Ships out very shitty ass products that breaks after 3 days of use

or the more likely

2. They purposefully ship out their old miners after cleaning because they oversold the miners or are turning over their old miners for new ones.


This would all be ok IF they told us that they sold used miners. But nope, I paid new miner money for old, broken miners.

I will keep you all updated on the RMA process after golden week!

It's a shame they sell old equipment branded as new. Is there another alternative supplier or do you recommend to buy miners rather from ebay if available?

There are a number of competitors, but sadly, Bitmain miners will always have the better numbers (efficiency, speed etc).

However, It may actually not be the most profitable if you are a small farm. Your chances of getting a bad batch, or bad machine is pretty much almost 100% in the long run. That plus the long wait time is something to think about.


Competitors:

Baikal
Innosilicon
Pinidea
Canaan Creative
BW.com
whatsminer
Ebang


anyone else got more lemon miners share in this thread!

It's a known fact Bitmain uses miners before shipping and to my knowledge they don't do anything about it even if you do happen to tell them about it. For Bitcoin, Ebit, Avalon and Bitfury miners if you can get your hands on them are better and probably not used. It's a shame that this, combined with expensive servicing if a miner breaks that makes Bitmain terrible to buy from. Not to mention it's them behind the recent and upcoming forks, which is more political.

Using miner before shipping is a standard testing procedure and nothing wrong.
I would prefer to get a preheated, pretested miner than one not tested at all.

Best way is to contact Bitmain or any manufacturer over the Internet and report all problems and attach
images, screenshots.

Making complaints on BCT makes no sense since buy/sell business is done between 2 parties, not in public.
It's not just that, but they mine for extended periods of time. It's known Canaan/Avalon test their miners and their own rigs on Kano and that is fine; their quality is good and the miners they sell aren't like some Antminers (and they don't mine for long periods of time with em Smiley). Bitmain also has terribly slow support and many times they reject perfectly good claims.

Only Bitmain considers running a machine for several months to be "standard testing" and not just, you know, using it. Been like that since the S5 days. I don't think they shipped out a single S5 that wasn't choked with dust.

Maybe they've updated their website ...

... but last time I looked I didn't see any references indicating what you are buying is "new".

We just rightfully assume it's new.

If I were them, I'd not even consider selling any of them, until after about 6 months of running, or when the next model is almost done, so you can flood the market with your used batch to finance ramping up production for the next version that'll take over the mining for another 6-12 months. For a project their size (production capacity) there's plenty of investors/funds willing to move large amounts of money to bankroll the operation.

If I were them I'd run them for about 1 day and then ship them to the next paying customer on the list. But most people consider raw profits over not being a self-serving ass. But that mindset tends to wreck economies in the long run. Course I also don't take money from investors/funds either, so I'm allowed to make my own decisions without others trying to buy the right to supercede me.

Oh, to clarify, it would be far from ethical, and I wouldn't call the company a production company, but a mining company that produces it's own equipment, then sells the used into the market once the in house produced new product is as good as done.

Why are you even mining Bitcoin? if you are not reverse engineering them to manufacture your own miners you are not earning any profit, you are just giving them more money, they will use that money to build miners to use for their own operations. Bitcoin is not for home miners any more.
Don't be stupid to think you are earning any thing, you are paying $1200 and how long would it take for you to earn back that money?

This makes me angry, why would they do that? That's like cheating the customers and I would not buy from them!

I am having the exact same issue as the original poster. I ordered 6 miners and the very next day I have 7 hash boards bad between 3 miners. The miners with the issue have 1.0.1.3 firmware the older firmware working fine.

I was offering a hypothetical Wink From a business perspective it makes sense to use first before selling, but as long as you've got superior material (in energy efficiency) it would be crazy not to let it run for a while before shipping. Then again, Bitmain should be honest about what they're doing before shipping. As was mentioned somewhere before, they don't explicitly state the hardware is new, but that is what you would reasonably expect Smiley

Ive been to bitmains hardware testing facility and watched them test miners. It is not a full on datacenter, and they do not run them very long. Also, at the end of the s7 production run they did advertise the last few batches as being used and they were offered at a discount because of this.

Stop buying industrial miners, running them at home, and then complaining about the noise.
