This listing is for Six (6) "Antminer U2" USB Bitcoin miners. Each one can hash up to 2 Gh/s, with proper cooling. All six miners together gives you about 12 Gh/s.
The hash rate is very low in today's mining standards. To be completely honest you will not make much money with these miners. Please do your own calculation and research before purchasing, to avoid any buyer's remorse. No returns.
I will ship the items within 2 business days. US domestic shipping and PayPal only. Thanks for looking!
