So isn't that a good thing?  Why didn't you lock the thread since they honored their agreement, and did in fact ship a miner to you as promised before the 20th?  Maybe put an "Update" or "Edit" that you made a premature mistake by implying that Bitmain was not being "Classy".

I don't think you thought this all the way through.

5.5TH = 11 S3+ units = ~6.3 BTC

AFAIC, an ATX supply to power these is reusable for other systems and has a strong resale market. (not so much for the server PSUs in an SP31). You might spend $700 to power 4kW, but could resell those supplies a year later for $400-500

besides, the S3+ B8 price was too high - i purposely did not buy any for that reason. At this point in the game prices for units that dont have a PSU and use <0.7w/GH should be around 1BTC/TH.   (Asicminer gear at 1.2w/GH has been selling for ~1BTC/TH almost two weeks now)


"If you want to compare them with the SP20's then 1.7 TH/s ± 10% @ $1,190.00 + PSU. 1100 W With a 0.9 Efficiency PSU."
4x S3+ units = 1.8TH / 1.4kW @ $1,120.00 + PSU  (expected to overclock easily to 1.9-2.0 TH) - Shipping before Sept 20 (at least 2 weeks before Spondoolies' 'October Shipping'

tl;dr - i agree that a lot of hardware right now is not going to ROI if we keep getting difficulty jumps >10%. The best ROI is to buy Asicminer equipment for less $/GH and run them in a location with cheap power. hopefully we see some in-stock sales and price competition next month

SNIP SNIP SNIP Was asking the dude that was calling SPtech hardware out... what about Antminer's S3's is the question. Don't need to hop on his question let him answer.

anyon fall into their bullshit ?
their hardware is waaaay to expensive to be worth investing in.even with free electricity you can't ROI...
only way it would be worth is to be at least half the price they are selling now
anything above ... just stay away, much better to just buy BTC

not that i'm advertising or anything, but you can just buy  antminers s3(like I did) instead, much cheaper,better efficiency and with shipping included !

Ok, so If you will build a farm, let's say in a room in your house (assuming all resources available, power, cooling...etc.), which hardware will you pick?

I own and operate an SP10 and two SP30s. Totally brilliant units. Spondoolies-Tech gear is top notch "server grade" equipment, and their customer service is the absolute best that I have encountered in the industry.

Just so you know, I've been mining 24x7 for the last 444 days*, and I also own gear from ASICMINER, Bitmain, Bitmine, BFL, and KnCMiner.

Since Spondoolies-Tech started selling miners I haven't found myself purchasing from another vendor. Not saying I won't (I quite like variety), but ever since I got my first SP10 I've been addicted to the build quality, form-factor, efficiency, and customer service.

And yes, they have always shipped on time. They cut it fine with the August Group buy, but I did personally receive my SP30s in the month of August, albeit at the very end of August... but still August. Some other companies (I won't mention who) will keep telling you that they will deliver in Two Weeks™, and deliver 6 months to 1 year late (you think I'm joking... I'm not). Then of course there are the scams that take your money and never deliver a product.

_{* I calculated the date I started mining and by pure chance as I post this it is 444 days since then.}

Shenzhen, 28 November 2013: Black Arrow releases the Preliminary datasheet of the Minion ASIC

---

Shenzhen, 26 September, 2013: Black Arrow is proud to announce that it has upgraded the specifications of its Minion chip to 100 Ghash (up to 128 Ghash when overclocked).

Prospero X-1 will scan 100Ghash while using less than 55 Watts and Prospero X-3 will be able to scan an outstanding 2000Ghash while using less than 1050 Watt.

More details here:
http://www.blackarrowsoftware.com/store/prospero-x-1.html
http://www.blackarrowsoftware.com/store/prospero-x-3.html
http://www.blackarrowsoftware.com/store/minion.html

Customers who have placed and paid the orders until now are offered a free upgrade while customers who have placed orders but not yet paid still have 5 days from today to benefit of the free upgrade.

Our Lancelot customers will continue to benefit of the initial prices until 5th of October. We have emailed all Lancelot customers with information on how to use the trade-in program.

We are currently offering 35% discount to customers who pay their order in full and 20% discount to customers who wish to pay 50% in advance and 50% before shipment. After October 2013 we will reduce the discounts gradually until they reach their full retail price which is $415 for Prospero X1 (100Ghash) and $6999 for Prospero X3 (2000Ghash).

Please note that February deliveries are limited because we will produce a limited number of wafers. The remaining orders will need to wait 1 month more until the 2nd batch.

The current discounts and offers are limited. The promotion will stop once we've covered the engineering costs. We do not aim to make any profit on our first batch of ASICs and our sole target is to cover the manufacturing costs. We have funded more than 70% of the NRE from our own funds. We can get the remaining 30% from various investors but we wish to give our customers the opportunity to benefit of low prices while helping us complete this project.

Shenzhen, 21 September, 2013: Black Arrow has now opened their web-store at www.blackarrowsoftware.com/store and are now taking pre-orders for the Prospero Bitcoin Mining Machines and their Bitcoin ASIC codenamed “the Minion”. The first orders are expected to be shipped at the end of February 2014.

Black Arrow is currently selling the Minion as low as $1.99/Ghash

Black Arrow Ltd has already a proven track record in successfully manufacture bespoke Bitcoin mining hardware at extremely competitive prices using shorter full lifecycle than their competition without compromising the top quality required the highly-competitive niche market.

Black Arrow’s expertise in software engineering, hardware design, manufacture and customer support lead to develop unique solutions addressed to technology savvy clients. Their customized solutions are encompassing the most advanced lithography. The end result is a strong contender for achieving a reliable mining and high revenue backed by reduced costs and with high expectations on the customer satisfaction front.

Black Arrow Ltd are actively monitoring the market to remain competitive and are seeking to become a major player in this field. They are currently offering an attractive offer: customers placing orders now will be protected against any price decrease prior delivery on the original price tag by being offered a proportional increase in hashing power at no extra charge. The sales model on the new line is attractive to their first customers who are guaranteed to receive a much improved deal.

The Prospero line includes two types of crypto currencies mining hardware products: Prospero (X-1) targeting individual customers and Prospero (X-3) targeting the much larger business community (datacenters).

The Prospero (X-1) machine features a compact and stackable design, out of the box functionality, ethernet connectivity and friendly UI with a performance of 64 Ghash/second.

The Prospero (X-3) machine is designed for high performance mining, is fully rack-able and presents out of the box functionality, ethernet connectivity and friendly UI with a performance of 1300 Ghash/second.

Black Arrow Ltd are currently offering a 25% discount on all preorders paid in September and October. The sales price (after applying the advertised discount of 25%) for a Prospero X-1 is $239 and for Prospero X-3 is $3999.

Stand by my statement. You LIE and you are sack of shit.

So your brother lied. He is now trying to force me to send him money by blackmailing my account. You are also involved in the blackmail.

What sums it up is.
Your brother ordered on the 5/2/2014 and when orderingm accepted the terms of the groupbuy that meant he was not elidgible for a refund after the order was sent for processing.

7/2/2014 curiousminer order sent for processing

Everything after this does not change the above. Your brother is not elidgible for a refund. You tried to force me to give you my personal information. You tried to blackmail me and you are trying to extort money from me. That is all proven in this thread and is the justification for the feedback I have left on your account and for my signature.

And at that point I feel since the accusing party is bring out no new information that this case has come to a conclusion and that my side of this issue in relation to the blackmail, extortion and slander will be covered in a seperate thread. If anyone would like to contact me in relation to this accusation I would ask you pm me as it is unlikely I will answer if it is posted here.

Regards, Beastlymac


The facts have been proven I have upheld and not broken the rules your brother agreed to. You having the audacity to call anyone else unprofessional in this situation is a joke as you and your brother have lied you have also attacked me personally and you have been impolite towards members of the community who have tried to assist in resolving this matter.

There are a number of unresolved issues with some customers as well as scores of customers that were poorly treated and lied to directly and this is well documented in the threads. I can not recommend a company that is unwilling to resolve customer complaints. If those who were burned are made whole then I am more than willing to change my opinion. At this point I don't see how that is going to happen given the stance of the company towards some of their customers. Given what passes as customer service it is not a company I would recommend based on even present threads in the last few weeks with regards to RMA's.

This is not a guide on how fast you come to market. It is a guide on how well you deal with the consumer bottomline and there are clearly persistent issues with this company and their treatment of consumers. I would never personally recommend a company that has outstanding issues with the community especially when you might even have suspicions they use multiple accounts to misrepresent their customer service. There is clearly an inordinate amount of NEW members posting on how great the Technobit service is. It is an anomaly that doesn't go unnoticed by senior members and should give you pause about the reality with that company especially given how many complaints there are right up to today.

As an example Avalon would be thumbs down until we are given the whole story of what went down during the chip fiasco last year. You can't rely on a company that has willfully ignored the community asking for accountability. As such you are much better off dealing only with companies that have proven trustworthy. Again my opinion but there is certainly less risk involved dealing with companies on the THUMBS UP side vs. the THUMBS DOWN side.

Bitmain or Rockminer does very well shipping almost real time with minimal delays / pre-order and at a reasonable price. Why not use them over a company that could be suspect? That to me is why you use this guide. You cut through the crap and get to the point. Who is reliable all the time. The pattern continues... be warned.

An official threat? That's new.....

Header typo me thinks.

I don't think we're going to see him in the States ever again.

Is goxxing allowed on this forum? Can't retard Josh Zipkin get a ban for this stunt?

Looks like he is desperate to change his image he is working overtime on the SEO efforts to craft his image.

https://angel.co/josh-zipkin

May as well had made that shit on geocities or angelfire. LOL

Liar. Guys full of shit.

Wow, having a follower here, too bad it is a McCarthy style imbecile like you. I don't like shops/manufacturers making claims they can't hold, I hate fools like you that thrive on that a thousand times more. Now, gfy okay?

I'll do a Kim Dotcom and make a custom "SP3000 Turbo" sticker for my SP30.
