Bitmain is pretty great.  Their produces are delivered on time or faster (± normal noise that happens with international shipping), and their products are exactly as specified. Their products are industrial workhorses. They do not come in a sleek plastic case with useless decorative lights, instead— they actually work.

I don't get the impression that they have a bunch of fluent English speakers around, so communication is sometimes a bit spotty. Some people who've had packages get stuck in customs or received the odd defective part have reported it taking a while to get it resolved.

Like all current mining hardware companies their prices are so/so in that you're making a gamble on future difficulty, though they've been diligently lowering the prices as the expected future income goes away.  But the fact that they deliver on-time and to-spec— what really should be table stakes— makes them stand out in the business of Bitcoin mining.

Bitmain sent me a 90GH/s prototype unit before they started shipping, with the current firmware antiminers are awesome on P2Pool. Subsequently, I purchased a couple more on my own as a regular customer. 

I've recommended the antminer S1 to friends, and if you're thinking about getting into mining for fun and to support the network, I'd still recommend them. (Actually looking to turn a profit at it— well, thats a more complex question)

I second this.

Sorry for my lack of knowledge with Bitmain, but about how long does it take from the time to order to receive it at your door? And are there faster shipping options?

Thanks

I ordered on Monday and they are already enroute via UPS to NY

Remember, don't invest what you can't afford to lose because *anything* could go wrong, you may indeed reach ROI but you may not depending on when you actually buy, the pool you use etc etc....no guarantees at all and if BTC goes down to half the price it is this morning well you can already imagine what that means.

Personally I don't trust the mining profit calculators and don't find them accurate compared to my actual real world results but again do NOT spend what you can't afford to lose as things are getting late in the game and soon 200 GH/s will be worthless. I have four of the Antminer S1 and can't see them being very profitable after another 60-90 days and their will come a point where power costs more and it will be better for me to sell them all and hope someone with a larger farm that doesn't pay power will want them. I may be wrong and perhaps they will last a bit longer but nobody really can be 100% accurate and if we get flooded with 2 TH/s miners soon that will affect things.

Don't forget the cost of power! I have a power monitoring system and can tell down to the cent what each watt cost and overclocked my Antminer S1's for two of them in my home are using 864 watts and I pay 6.99 kWh this month so I am paying about $1.40 for two units per day and $2.80 for all four of mine per day to run 24/7.

Simple math says all 4 of my units will cost me $84 in power this month but what if next month my power goes to 12.35 kWh which alot of times does happen, well then I pay double the cost for power. I am currently making about $60-80 per day on average from what I can tell however difficulty is increasing and this will get less and less so I don't need to say it again because I already warned you twice about your investment. :-)

I cannot post a image and get an error "invalid proxy" when using imgur otherwise I would show a capture of my power usage for two Antminer S1, I'm sure others get the same numbers as I do in regards to power usage etc.

Good luck!

Man, you are too serious about this

For me, BTC is pretty undervalued right now (limited 22M supply; still widespread mainstream skepticism, even more after Gox; less than 400K wallets with > 1BTC as of Jan/Feb etc etc). Actual daily volume of BTC is also pretty low since most people who hold bitcoins are pretty stubborn holders, so the low daily liquidity is not reflecting the true value. So in all my ROI calculations, I assume a much higher floor than the current $600-ish value, but that's 3-5 years out and I'm really patient (have yet to even sell my Amazon stock from 1999).

But you may have a different time horizon.

I'm terrified to buy the s1, I was reading the set up and trouble shoot and now I'm worried I won't be able to set it up....

My Ant S1 came today, also delivered was a bookcase that I'd ordered from Overstock: One of them was a pain in the ass to set up.
Thanks in large part to this forum...it wasn't the Antminer ;-) < that went smoothly. If you are a (slightly above) basic user of computers and can follow directions you'll be fine  

There were no duty or other fees for me (I'm in the U.S.) Shipping was included in the Bitmain price

[Peacefrog]

Does bitmain also charge you for shipping? I didnt want to place an order just to find out

[Suave]

+1 for bitmaintech!!

[Und3rd0g]

I ordered my S1 from bitmaintech on March 6.  It shipped on March 8.  Arrived at my door in the US on March 12 (that included a one day weather delay by UPS). 

As already stated, +1 for bitmaintech!!!

Nope.  Shipping is included in the purchase price.

shipping is included as well as support and return shipping within the 90 day warranty period if something fails.

Awesome thank you. I had 1 more question. I know what kind of power supply i would need (i actually had a cx650 on hand) but the wording on bitmaintech sounds like it comes with a power supply

[AngusCanine]

I thought the same thing

[AngusCanine]

Here's the wording "Power effective: Saving the investment of PSU, cable and the cost of electricity bills."

[t3c]

Is anyone selling these directly in the UK, i'm sure i went to a site 2 days ago who were but can't seem to find it any longer

[Skaterdiejosh]

No they dont come with power supplies i recomend this one for running 2 antminers not over clocked!!

Dont buy a cheaper one I have a cheaper 850 watt power supply and it kicks out twice the amount of heat !!!

[AngusCanine]

I just bought an S1!!!!!!! And I don't care what my wife says .  I'm stoked can't wait to get home from working in the frozen north to set them up. Should get back just in time, the wife will be over her shock and should be able to set it up with out the feeling of piercing eyes  thinking about strangling.....

I'm running 10 off 5x CX750M, no issues.
Swapping them all out to have 3 on 1200W HP Server PSU's though... Can't beat it for $20/1200W

Oh no my order expired even though the bit coin went through  . Fuck I hope my wife doesn't get the last laugh  .
Anybody have an thoughts on this?

What do you mean by "expired"?   Bitmain is very reliable.  Be patient. My last order didn't show it was "shipping" on their website until 2 days after it shipped. Good luck!

Its never easy to watch your money in limbo , the order expires after an hour if they haven't received payment, even though I sent the bitcoin immediately it expired and show unpaid, was a long night thinking about my wife telling me  " I told you so" , but this morning it says paid. So everything good I guess they will manually send the order is what I  got from a prompt message return here in the forum from bit main.
