Anyone using the Umisoo hosting service? I would love to hear some feedback, it seems like a great option considering the shipping of these things are almost the cost of one unit.
I took the Umisoo option to avoid shipping and customs on my S4s, so I can't say if it would be the same experience as with the S3s, but overall I'm happy with the service. It's pretty reasonable; they basically charge $0.13/kwh including all power/maintenance, then it'll reduce to $0.12 at the end of Dec, then another drop to $0.11 in the spring.
My ants have been running well for the past month aside from one glitch where I had to reset my pools to get one of my S4s back online. The nice thing is you end up using the same account as Bitmain, and shipping/delivery/installation is pretty seamless.
Depending on how much control you like to have over your hardware, the web interface is a little lacking; they just have 3 sets of pool, worker ID and password for each miner. Maybe they'll give us direct access to miners in the future (or maybe you just need to ask), but if I had S3s there, I'd prefer to be able to overclock them.
Communication is more than a little cryptic (they refer to miners as "mills" for some reason) but overall communication has been solid, letting me know when they were online and ready for me to enter pool info.
Overall, I'm very happy with my decision, but obviously there's room for improvement!
