Antminer L7 worked well for me!
I will recommend minerbases to all. I had a video call with them before I placed the Antminer L7 order. They has a wonderful office and over 40 staff. I was worried at the beginning because the price of miner is very high until I saw their real office and license. The customer service was so friendly and answered many questions for me. My L7 works well so far. I hope everything goes well in future. Right now I am living in HongKong. Their Office is very close to my home. So, I can go and clarify myself regarding any issue related to my devices and mining. Although I am satisfied, I have a bit confusion about their customer support system. They should have a 24 hours live chat system for the customers/partners like us.
