What are you saying great job for? They have a prototype no miner to sell to general public, heck I don't think we even know efficiency of prototype. So there is not a lot of good things.
I would avoid company till they prove a lot more. Also I would want to see possibly a better design look at their site when it's hooked up near water heater. That is just something most "home miners" won't be able to do on install I dont think.
