Are Group Buys allowed? I'll collect enough to order 300+ units. Then everyone in my Group Buy will enjoy the lower pricing. Also, Mr. DualMiner, I get to keep the sample unit? The delivery dude made me pay customs/duties/taxes/docs/whatever. cgminer console window ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FgqR0hwO.png&t=665&c=5VZcj6JYXbVyhw) Maybe because I'm mining another coin, the numbers look odd. But the pool stats seem to match. I'll keep it running for a few hours. This thing already beat my CPU mining using 10 CPU's in my office.

To all DualMiner USB reviewers, thank you for providing your independent review about our USB miner. You are more than welcome to keep the sample units for yourself. Have fun!

Sorry no matter how expensive your electricity is, you are paying $980 for 700Kh of LTC mining when you can get that for half the price in a GPU.
At 500 watts for a single GPU giving you 700Kh you would pay $54 a year (at $0.15 Kwh) to run it.
The breakeven on the electricity would require you to mine for 7-9 years before these devices recovered their excessive cost.
For easy math, a GPU of about 700Kh mining costs $500 (for round numbers) so for these to be competitive they have to cost $50 USD
When they hit that price (or close to it) you should buy all you can get. There is a small window then Alpha T starts selling their units.
Just my 0.02BTC
your math wrong. 0.5kw * 365 days *24 hours * 0.15Kwh = $657 But 7970's power consumption is 280w, not 500 So 0.28 * 365 days * 24hours * 0.15Kwh = $367,92 - electricity cost per year 280 Watts. Let's convert this number to kiloWatts by dividing by 1000, to get 0.28 kiloWatts. These devices, that have been on for 24 hours, have consumed 0.28 Watts × 24 hours = 6.72 kWh (kiloWatt-hour) of energy. Finally, since energy costs you $0.15/kiloWatt-hour, these devices have costed you: 6.72 kWh × $0.15f/kWh = $1.01 a day * 365 days = $368.65 to run a GPU for a year Which gives you 700Kh? Now instead you buy 10 of the USBs and run them LTC only and you have spent $980 Let's say they use 20 watts a day ($0.07 a day) or $25 a year to run $980 + 25 = $1005 for 700Kh is total operating for a year for these. A GPU of the 7970 type is $440 plus the $368 for electricity is $808 cost to operate for a year. Both the GPU and the USB Dual miners require a computer so we wont add those in and we wont add in the $80 for a good USB hub to run 10 of them. First add import taxes. Then do the math ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

What results were you getting with 10 units on a USB hub for scrypt? 70kh/s x 10 or were there any minor drops? interested in 200 or 300 depending on import duties. will need to double check.

Just keep watching, the first few are in the hands of some Sr members here for testing, then a little later the rollout. Interesting beginning for alt coins.

will definately buy some when the price comes down a bit.
~0.060BTC or so and I will buy, much easier than setting up an scrypt rig

My power consumption is becoming insane ( nearing 3kwh ) so I'll gladly do the math for me to see if it's beneficial.
For me 1kw electricity 24/7 31days is 178euro.
My 4* 280x rig uses ~1.110kwh and delivers 2.88MH ( including setup ) 41* Dual miners would use ~ 103kwh and devilers 2.87MH (excl setup , anker usb hub + fan uses ~3.5w )
So my electricity cost just went from ~200e to ~19e , let's say I am saving 180e a month
Cost : full 280x setup ~1600e full dual miner setup : ~4000euro excl shipping+taxes
so a ROI of over a year.

You should be able to build cheaper high hashing rate LTC only miner with DualMiner USB. Please remember, DualMiner USB are priced with volume discount; * Price (per unit) 1~9 $98 ea. Full Price (FP) 10~49 $92.12 ea. 94%FP 50~99 $88.20 ea. 90%FP 100~299 $83.30 ea. 85%FP >=300 $79.38 ea. 81%FP Try your best to take the advantage of our volume discount program. Our Chinese partner uses lots of Orico P10-U2 USB2.0 hub, which you could get it for low $20s/unit, for its production testing purposes. Each Orico P10-U2 could host 10 DualMiner USB devices for mining. So, you could build your own 4.2Mh/s miner with 60 DualMiner USB devices + 6 P10-U2 hubs with the cost of $4762.8 (60x79.38, assuming you could get the unit price $79.38 for each DualMiner USB) + $175($25x7) = $4937.8.
