Overclocks to 2.0 (sometimes only 1.9) like it was meant to, just aim a fan at your collection of them. Almost ZERO hardware errors for a week straight of mining, some actually are zero, but a few doesn't hurt. I think these are more reliable than the new U2's by quite a ways. Buy from Jones Gear, they are the best! No prime but REAL fast shipping.

Jonesgear is without a doubt the BEST in delivery and offering a Fantastic product!If your getting into ASIC mining, pick up at least 6 of these to start your mining rig with. I currently have each of my cards over clocked to 1.9 G/H. You can go up to 2.1, however, 1.9 seems to work best for me without any HW errors.6 running at 1.9 G/H is giving me 12 G/H speed. I have 6 more coming and plan on getting 6 more from Jones Gear :)FYI: Very Low Power Consumption! This is a major plus :)

First dedicated mining tech I ever bought. Now basically obsolete, expensive electric heater.

I picked up a few of these to replace the older USB Block Erupter's (Slower hash rate than the U1 of ~333MH/s) I had in my mining system. It was nice to free up some space in my USB Hubs, since each of the U1's take the place of roughly 5 of the Block Erupter's.Setup was simple on a MacBook Pro running 10.9, only requiring an update to bfgminer to support the U1. Overclocking these is also pretty simple (it's simply a switch on the bfgminer command line), and pushes the clock rate over 2GH/s while still remaining stable (at least for me, with ample cooling).I'd recommend the U1 for any hobbyist, but at ~1.6-2.0+ GH/s , don't expect to make a whole lot of BTC if you go that route given the current difficulty levels.

this thing has been clocked to 2gh and is running strong on triple mining.. excellent. i want more. 20th word.

Was a great buy.... have had them online since I got them. It is well worth the price if it remains around 50 dollars.

Get U2s

This is a really cool product. I used it to turn a Raspberry Pi into a cryptocurrency miner. It works with both CGMINER and BFGMINER and it is pretty easy to setup if you are comfortable with Linux. Since the purpose of a miner is to run all of the time, I also set up the Pi to run a Spigot Minecraft server and use screen to start both the miner and the server. If you are running a server of any type adding one of these Antminers is just a cool thing to do.I bought mine from JonesGear, which is an excellent company to do business with. You can read this in multiple reviews on Amazon and in blogs where cryptocurrency mining people post. Jones has fair prices, ships lightning fast, and the products are exactly as promised. If you go to their website and read blogs you also see that they excel at customer service. They answer customer questions and even encourage people to call with their questions. When I contacted them through Amazon they answered me both times within 12 hours. I buy items from Amazon because I have always had great customer service with Amazon. As an Amazon reseller, Jones seems to have that same philosophy that customer service matters. I don't usually write reviews but these are stand up people. I believe in giving business to people who demonstrate that they deserve business. If you are choosing between some stranger on ebay and JonesGear it is really a no brainer. Go with JonesGear.
