Want to try mining? Buy 2 (1 + a spare) and go have fun, the online community is great, but don't do this for the money. I've learned a lot too.
1) There are absolutely no directions so you are on your own. It is not too hard to get it working though. It took me about 20 minutes to figure where to get a driver; download it; install and get it working without overclocking.
2) It runs hot even without overclocking so I am not too keen on running it even hotter.
3) It does about 1.6 Gh/s with the driver I got which is the U1 driver since I couldn't find a U2 driver.
I say it is not bad so far. Don't expect miracles and you won't be disappointed.
However I doubt that it will make any real money since the rate of mining with one of these is about 0.005 bitcoins per month with today's difficulty. As we know the rate will keep dropping so in about 200 months I will have a bitcoin :-)
On the other hand it makes a lot of heat and where I live is pretty cold. If you take the free heat into account then a bunch of these may be a self funding heater.
--anu-freq 280 which runs it about 2.2gh/s per ASIC miner. That setting keeps me at about 4.450gh/s which varies from time to time but still a steady average of 4gh/s (two U2 miners). I use p2pool and not going to get rich, lol but makes 50+ cents every 10 hours. I just order two more of these so yes I am pleased with their performance. I will mention that running it using cgminer4.3.3 I do get HW Errors but I just pay no mind to them because 1 can't find a way to get 0 HW Errors and as I read this happens to many people and their miners are doing fine. 2nd performance of this and probably any miner is dependent on your system as a whole. I run Win7 Home Pre. 3ghz 8gigs ram 64bit w/slow DSL internet(2+mbs dwnload). I am waiting for all parts to arrive and will soon be using my Rasberry Pi with MinePeon to run miners..
For the size of the miner is just amazing for what it Hashes at it is said to be able to clock at 2Gh/s and i can say that the name is a little misleading because sometimes you might be able to clock that high.
I got about 1.8Gh/s overclocking it. Don't forget that you might not get the same clock as me you could get more or less.
The mining Client i would suggest to mine with this is Bitminter it just makes everything a lot easier.
If you look for some videos on youtube you can find ones to setup a asic miner on Bitminter.
i gave this it's rating because it performs well and its amazing for the size, and i also only gave it a 4 star because the title is misleading and sometimes doesn't reach its description and you can only get a stable clock at 2Gh/s sometimes.
Happy Mining everyone .
These little guys are great to use to get a few tidbits of Bitcoin but also brag about your "Huge" Bitcoin Mining Farm at the Local Water Cooler, if the IT Guys start gassing off! :)
Quick, Fast and well packaged shipment arrived shortly after placing the order!
