After expressing interest in purchasing the SP20, I received an invoice generated by Quickbooks from DG Rollins Mining, LLC. The invoice was for the cost of the unit, plus a month's hosting costs. OM agreed to run the unit underclocked, and charged me accordingly. I paid the invoice using bitcoin. I checked my pool about 10 minutes later, and the miner was already running. Other than the downtime mentioned above, the miner has run consistently and at the expected speed.
The one service I wish they offered is the ability to change pools myself through a web interface or something similar. Hopefully this is something that can be added in the future. That said, I haven't had a need to change pools yet, and OM has said that they will change pools upon request. However, especially with hosted services, I like to test out how the miner responds at different pools, so this would be a helpful added feature. I should add that Lee, who I suppose is their competitor, also does not offer this service.
Overall, I'm happy with my experience with OM. It appears to be a professionally run operation.
Thanks for taking the risk
What's the underclocked performance?
It ranges from 1.38 Ths to 1.42 Ths at the pool, just about what I expected.
