Question: Brand new. 4th Generation Revision. Ships immediately. Multiple colors available. I thought Saphire was third gen. Did you forget to update you add?
Document: Got mine from Jones Media for about $50. As advertised, came well packed brand new with a website to check for instructions. Up and running in about 5-10 minutes, hitting 330+mhps. This is not a get rich quick scheme, but if you're wanting to get into BTC mining right now it's the most cost effective route I believe. We'll see how it performs over time and I'll update this entry.
Fantastic Seller!! The ASIC Miner arrived securely packaged and with no damage, It was in fact brand new and still sealed shut. I took it out and plugged it in, installed the drivers and started with BitMinter. After a weeks worth of constant mining, I am averaging about 338 MH/s which is excellant.
There's also an added benefit to using these as opposed to buying a larger, more expensive mining rig. If one burns out, you don't have to spend several thousand dollars replacing your whole rig, you can just spend a few bucks and buy a new unit and swap it out for the old one. Also going along with the whole modular idea, you can easily add to your hashing power by just adding another unit to your setup.
Product does what it says in the description, and is as i expected.Easy to use, and i have had no problems with it.Pulls 500mA at 5volts, temperature is high so I will add additional heat sinks, in order to possibly extend the lifespan of the product.
Came new in box, had some trouble with the USB/Serial drivers, but after that they work like a charm. Now I just need more!
This product is well designed and worked immediately in Ubuntu with BitMinter. They also worked with cgminer. I have two of these and both get around 335 MH/s. They do run hot and if you want them to last you should have a small fan to cool them.The only issue here is profitability. Power consumption is very low so this is not really a factor.
If you can get these for under $20 then it's a good way to figure out how to mine. Much better options available now.
For my purposes these units work perfectly well. I had been interested in the concept of Bitcoin mining for a while and had started mining with several video cards that I had available at the time. When Block Erupters dropped down to a reasonable price a picked up a few to investigate how they worked. They have served that purpose and have also made me a little more Bitcoin while doing it.
What can I say, I've been following bitcoin for a while now. I saw this while researching some of the new hardware coming out. This was an easy way to get started with minimal upfront investment. It may take 6 months to break-even but I'm not looking at this as an investment opportunity. It's a hobby and a way to acquire coins (or fractions of them)...Setup was quick and easy once I got my parameters right.
212 days Breakeven is the new rate because of the increase in price for Bitcoins. You followed my advice and invested directly in Bitcoins, right? If so, you're looking at a VERY nice return of hundreds of percent. If not, you're watching this "hobbyist" device generate fewer and fewer bitcoins. You're choice, what are you going to do?EDIT:1/27/14 - I certainly hope that people aren't still looking at these devices. I mean, why bother?
Answer: If it is "Sapphire" it is second/third generation at 330-350 Mh/s. The blue PCB is a third gen feature. And if it is 4th generation the price will be relatively much higher as this would be a chip that has not been released yet, with unknown specs
