I signed a 6-month contract and sent in an SP30 to ASICSPACE. When it arrived, ASICSPACE found that my PSU's had been replaced at some point and had C19 outlets instead of C13. ASICSPACE had suitable adapters express delivered for me free of charge. Later, the Bitcoin price tanked and I decided that I would like to sell my SP30 instead of host it. ASICSPACE allowed me to cancel my 6-month contract even though they had the right to repossess my hardware if I did not pay for the full 6-month term. All around great customer service.
