I've been with Minerack for 2 months now I think, and they are great! I have the Iron Tier (2gigs).
If I ever have a problem, they help me out right away. I'm paying half the price I was paying with my last provider, for double the ram Plus, my old provider had many problems with huge lag and server crapping out, which if this one does, it's remedied asap.
I've been impressed with how well they run this company, and that's why I'm leaving a review.
If you have any questions regarding my experience with Minerack, feel free to PM me.
Worst service I have ever received. 0/10 would not recommend.
They were good for the first 3 months and then all went to crap. Never buy from these guys.
