If GAW follows their trend of screwing customers, you'll see a 60% decrease in hashlet price within 2 months and an increase in difficulty so high that you might make it out with 50% return before your hashlet(s) are worthless.
Congrats!
They actually raised in price form $15.99 --> $19.99/mh since I bought them. This 50 mh would now cost $999.99 when I only paid $799.99.
